Abstract
Summary and conclusion
The aim of this study is to assess the accuracy of magnetic resonance imaging versus computed tomography in diagnosis of nasopharyngeal mass.
This study was done during the period from June 2002 to December 2003 in Radiology Departments, Zagazig University Hospitals. The study included 30 patients, 19 males and 11 females, their ages ranged from 5 to 69 years.
The patients were subjected to:
1- Clinical examination.
2- CT scanning.
3- MRI
4- Histopathological analysis.
The lesions encountered in our study were classified into 22 malignant lesions and 8 of benign nature.
The malignant lesions were further subdivided into tumors arised from the nasopharynx itself, they were squamous cell carcinoma in 12 patients, lymphoma in 8 patients, and malignant tumors extended to the nasopharynx in the form of chordoma and carcinoma of the maxillary sinus.
Eight patients with benign lesions were included in our series, further subdivided into 6 cases arised from the nasopharynx, they were 3 cases of angiofibroma, 3 cases of adenoids, or direct extension from adjacent structures in two cases, one case of nasal angiofibroma and the other was pleomorphic adenoma of the deep part of the parotid gland.
Both CT and MRI were done for all our patients, CT was effective in the determination of the lesion, extension, other close association, the bone destruction and abnormal calcifications inside the tumor, however CT failed to distinguish between the tumor itself and the surrounding soft tissue structures.
MRI is a sensitive technique in good differentiation between the tumor itself and the surrounding structures, the extension and the obliteration of the surrounding spaces, MRI has also good advantages of determination of the intracranial extension.
In conclusion:
The Computed Tomography is effective in imaging of the nasopharyngeal lesions as if they are primarily arise from or as an extension from the parapharyngeal structures. It also provides a good details about the nature of the lesion, density, extension and other association and presence of calcifications or bone destruction, which is deficient in MR imaging.
The advantages of MR imaging with its superior soft tissue contrast resolution, absence of bone hardening artifacts, and ability to image in multiplanner fashion has allowed to image the deep fascial structures as well as the distinction between the tumor and the surrounding soft tissue is easier than that of computed tomography.
So both CT and MRI are well-established methods in diagnosing diseases of the nasopharynx and its surrounding.
The recommended diagnostic strategy for mass lesions of the nasopharynx and surrounding structures is to use Gd-enhanced MRI as a primary study and contrast enhanced CT as a secondary study for the evaluation of fine bony details.

The Computed Tomography is effective in imaging of the nasopharyngeal lesions as if they are primarily arise from or as an extension from the parapharyngeal structures. It also provides a good details about the nature of the lesion, density, extension and other association and presence of calcifications or bone destruction, which is deficient in MR imaging.
The advantages of MR imaging with its superior soft tissue contrast resolution, absence of bone hardening artifacts, and ability to image in multiplanner fashion has allowed to image the deep fascial structures as well as the distinction between the tumor and the surrounding soft tissue is easier than that of computed tomography.
So both CT and MRI are well-established methods in diagnosing diseases of the nasopharynx and its surrounding.
The recommended diagnostic strategy for mass lesions of the nasopharynx and surrounding structures is to use Gd-enhanced MRI as a primary study and contrast enhanced CT as a secondary study for the evaluation of fine bony details.
Summary and conclusion
The aim of this study is to assess the accuracy of magnetic resonance imaging versus computed tomography in diagnosis of nasopharyngeal mass.
This study was done during the period from June 2002 to December 2003 in Radiology Departments, Zagazig University Hospitals. The study included 30 patients, 19 males and 11 females, their ages ranged from 5 to 69 years.
The patients were subjected to:
1- Clinical examination.
2- CT scanning.
3- MRI
4- Histopathological analysis.
The lesions encountered in our study were classified into 22 malignant lesions and 8 of benign nature.
The malignant lesions were further subdivided into tumors arised from the nasopharynx itself, they were squamous cell carcinoma in 12 patients, lymphoma in 8 patients, and malignant tumors extended to the nasopharynx in the form of chordoma and carcinoma of the maxillary sinus.
Eight patients with benign lesions were included in our series, further subdivided into 6 cases arised from the nasopharynx, they were 3 cases of angiofibroma, 3 cases of adenoids, or direct extension from adjacent structures in two cases, one case of nasal angiofibroma and the other was pleomorphic adenoma of the deep part of the parotid gland.
Both CT and MRI were done for all our patients, CT was effective in the determination of the lesion, extension, other close association, the bone destruction and abnormal calcifications inside the tumor, however CT failed to distinguish between the tumor itself and the surrounding soft tissue structures.
MRI is a sensitive technique in good differentiation between the tumor itself and the surrounding structures, the extension and the obliteration of the surrounding spaces, MRI has also good advantages of determination of the intracranial extension.

Eight patients with benign lesions were included in our series, further subdivided into 6 cases arised from the nasopharynx, they were 3 cases of angiofibroma, 3 cases of adenoids, or direct extension from adjacent structures in two cases, one case of nasal angiofibroma and the other was pleomorphic adenoma of the deep part of the parotid gland.
Both CT and MRI were done for all our patients, CT was effective in the determination of the lesion, extension, other close association, the bone destruction and abnormal calcifications inside the tumor, however CT failed to distinguish between the tumor itself and the surrounding soft tissue structures.
MRI is a sensitive technique in good differentiation between the tumor itself and the surrounding structures, the extension and the obliteration of the surrounding spaces, MRI has also good advantages of determination of the intracranial extension.
In conclusion:
The Computed Tomography is effective in imaging of the nasopharyngeal lesions as if they are primarily arise from or as an extension from the parapharyngeal structures. It also provides a good details about the nature of the lesion, density, extension and other association and presence of calcifications or bone destruction, which is deficient in MR imaging.
The advantages of MR imaging with its superior soft tissue contrast resolution, absence of bone hardening artifacts, and ability to image in multiplanner fashion has allowed to image the deep fascial structures as well as the distinction between the tumor and the surrounding soft tissue is easier than that of computed tomography.
So both CT and MRI are well-established methods in diagnosing diseases of the nasopharynx and its surrounding.
The recommended diagnostic strategy for mass lesions of the nasopharynx and surrounding structures is to use Gd-enhanced MRI as a primary study and contrast enhanced CT as a secondary study for the evaluation of fine bony details.
Summary and conclusion
The aim of this study is to assess the accuracy of magnetic resonance imaging versus computed tomography in diagnosis of nasopharyngeal mass.

The aim of this study is to assess the accuracy of magnetic resonance imaging versus computed tomography in diagnosis of nasopharyngeal mass.
This study was done during the period from June 2002 to December 2003 in Radiology Departments, Zagazig University Hospitals. The study included 30 patients, 19 males and 11 females, their ages ranged from 5 to 69 years.
The patients were subjected to:
1- Clinical examination.
2- CT scanning.
3- MRI
4- Histopathological analysis.
The lesions encountered in our study were classified into 22 malignant lesions and 8 of benign nature.
The malignant lesions were further subdivided into tumors arised from the nasopharynx itself, they were squamous cell carcinoma in 12 patients, lymphoma in 8 patients, and malignant tumors extended to the nasopharynx in the form of chordoma and carcinoma of the maxillary sinus.
Eight patients with benign lesions were included in our series, further subdivided into 6 cases arised from the nasopharynx, they were 3 cases of angiofibroma, 3 cases of adenoids, or direct extension from adjacent structures in two cases, one case of nasal angiofibroma and the other was pleomorphic adenoma of the deep part of the parotid gland.
Both CT and MRI were done for all our patients, CT was effective in the determination of the lesion, extension, other close association, the bone destruction and abnormal calcifications inside the tumor, however CT failed to distinguish between the tumor itself and the surrounding soft tissue structures.
MRI is a sensitive technique in good differentiation between the tumor itself and the surrounding structures, the extension and the obliteration of the surrounding spaces, MRI has also good advantages of determination of the intracranial extension.
In conclusion:
The Computed Tomography is effective in imaging of the nasopharyngeal lesions as if they are primarily arise from or as an extension from the parapharyngeal structures. It also provides a good details about the nature of the lesion, density, extension and other association and presence of calcifications or bone destruction, which is deficient in MR imaging.
The advantages of MR imaging with its superior soft tissue contrast resolution, absence of bone hardening artifacts, and ability to image in multiplanner fashion has allowed to image the deep fascial structures as well as the distinction between the tumor and the surrounding soft tissue is easier than that of computed tomography.
So both CT and MRI are well-established methods in diagnosing diseases of the nasopharynx and its surrounding.
The recommended diagnostic strategy for mass lesions of the nasopharynx and surrounding structures is to use Gd-enhanced MRI as a primary study and contrast enhanced CT as a secondary study for the evaluation of fine bony details.

The Computed Tomography is effective in imaging of the nasopharyngeal lesions as if they are primarily arise from or as an extension from the parapharyngeal structures. It also provides a good details about the nature of the lesion, density, extension and other association and presence of calcifications or bone destruction, which is deficient in MR imaging.
The advantages of MR imaging with its superior soft tissue contrast resolution, absence of bone hardening artifacts, and ability to image in multiplanner fashion has allowed to image the deep fascial structures as well as the distinction between the tumor and the surrounding soft tissue is easier than that of computed tomography.
So both CT and MRI are well-established methods in diagnosing diseases of the nasopharynx and its surrounding.
The recommended diagnostic strategy for mass lesions of the nasopharynx and surrounding structures is to use Gd-enhanced MRI as a primary study and contrast enhanced CT as a secondary study for the evaluation of fine bony details.
Summary and conclusion
The aim of this study is to assess the accuracy of magnetic resonance imaging versus computed tomography in diagnosis of nasopharyngeal mass.
This study was done during the period from June 2002 to December 2003 in Radiology Departments, Zagazig University Hospitals. The study included 30 patients, 19 males and 11 females, their ages ranged from 5 to 69 years.
The patients were subjected to:
1- Clinical examination.
2- CT scanning.
3- MRI
4- Histopathological analysis.
The lesions encountered in our study were classified into 22 malignant lesions and 8 of benign nature.
The malignant lesions were further subdivided into tumors arised from the nasopharynx itself, they were squamous cell carcinoma in 12 patients, lymphoma in 8 patients, and malignant tumors extended to the nasopharynx in the form of chordoma and carcinoma of the maxillary sinus.
Eight patients with benign lesions were included in our series, further subdivided into 6 cases arised from the nasopharynx, they were 3 cases of angiofibroma, 3 cases of adenoids, or direct extension from adjacent structures in two cases, one case of nasal angiofibroma and the other was pleomorphic adenoma of the deep part of the parotid gland.
Both CT and MRI were done for all our patients, CT was effective in the determination of the lesion, extension, other close association, the bone destruction and abnormal calcifications inside the tumor, however CT failed to distinguish between the tumor itself and the surrounding soft tissue structures.
MRI is a sensitive technique in good differentiation between the tumor itself and the surrounding structures, the extension and the obliteration of the surrounding spaces, MRI has also good advantages of determination of the intracranial extension.

Eight patients with benign lesions were included in our series, further subdivided into 6 cases arised from the nasopharynx, they were 3 cases of angiofibroma, 3 cases of adenoids, or direct extension from adjacent structures in two cases, one case of nasal angiofibroma and the other was pleomorphic adenoma of the deep part of the parotid gland.
Both CT and MRI were done for all our patients, CT was effective in the determination of the lesion, extension, other close association, the bone destruction and abnormal calcifications inside the tumor, however CT failed to distinguish between the tumor itself and the surrounding soft tissue structures.
MRI is a sensitive technique in good differentiation between the tumor itself and the surrounding structures, the extension and the obliteration of the surrounding spaces, MRI has also good advantages of determination of the intracranial extension.
In conclusion:
The Computed Tomography is effective in imaging of the nasopharyngeal lesions as if they are primarily arise from or as an extension from the parapharyngeal structures. It also provides a good details about the nature of the lesion, density, extension and other association and presence of calcifications or bone destruction, which is deficient in MR imaging.
The advantages of MR imaging with its superior soft tissue contrast resolution, absence of bone hardening artifacts, and ability to image in multiplanner fashion has allowed to image the deep fascial structures as well as the distinction between the tumor and the surrounding soft tissue is easier than that of computed tomography.
So both CT and MRI are well-established methods in diagnosing diseases of the nasopharynx and its surrounding.
The recommended diagnostic strategy for mass lesions of the nasopharynx and surrounding structures is to use Gd-enhanced MRI as a primary study and contrast enhanced CT as a secondary study for the evaluation of fine bony details.
Summary and conclusion
The aim of this study is to assess the accuracy of magnetic resonance imaging versus computed tomography in diagnosis of nasopharyngeal mass.

The aim of this study is to assess the accuracy of magnetic resonance imaging versus computed tomography in diagnosis of nasopharyngeal mass.
This study was done during the period from June 2002 to December 2003 in Radiology Departments, Zagazig University Hospitals. The study included 30 patients, 19 males and 11 females, their ages ranged from 5 to 69 years.
The patients were subjected to:
1- Clinical examination.
2- CT scanning.
3- MRI
4- Histopathological analysis.
The lesions encountered in our study were classified into 22 malignant lesions and 8 of benign nature.
The malignant lesions were further subdivided into tumors arised from the nasopharynx itself, they were squamous cell carcinoma in 12 patients, lymphoma in 8 patients, and malignant tumors extended to the nasopharynx in the form of chordoma and carcinoma of the maxillary sinus.
Eight patients with benign lesions were included in our series, further subdivided into 6 cases arised from the nasopharynx, they were 3 cases of angiofibroma, 3 cases of adenoids, or direct extension from adjacent structures in two cases, one case of nasal angiofibroma and the other was pleomorphic adenoma of the deep part of the parotid gland.
Both CT and MRI were done for all our patients, CT was effective in the determination of the lesion, extension, other close association, the bone destruction and abnormal calcifications inside the tumor, however CT failed to distinguish between the tumor itself and the surrounding soft tissue structures.
MRI is a sensitive technique in good differentiation between the tumor itself and the surrounding structures, the extension and the obliteration of the surrounding spaces, MRI has also good advantages of determination of the intracranial extension.
In conclusion:
The Computed Tomography is effective in imaging of the nasopharyngeal lesions as if they are primarily arise from or as an extension from the parapharyngeal structures. It also provides a good details about the nature of the lesion, density, extension and other association and presence of calcifications or bone destruction, which is deficient in MR imaging.
The advantages of MR imaging with its superior soft tissue contrast resolution, absence of bone hardening artifacts, and ability to image in multiplanner fashion has allowed to image the deep fascial structures as well as the distinction between the tumor and the surrounding soft tissue is easier than that of computed tomography.
So both CT and MRI are well-established methods in diagnosing diseases of the nasopharynx and its surrounding.
The recommended diagnostic strategy for mass lesions of the nasopharynx and surrounding structures is to use Gd-enhanced MRI as a primary study and contrast enhanced CT as a secondary study for the evaluation of fine bony details.

The Computed Tomography is effective in imaging of the nasopharyngeal lesions as if they are primarily arise from or as an extension from the parapharyngeal structures. It also provides a good details about the nature of the lesion, density, extension and other association and presence of calcifications or bone destruction, which is deficient in MR imaging.
The advantages of MR imaging with its superior soft tissue contrast resolution, absence of bone hardening artifacts, and ability to image in multiplanner fashion has allowed to image the deep fascial structures as well as the distinction between the tumor and the surrounding soft tissue is easier than that of computed tomography.
So both CT and MRI are well-established methods in diagnosing diseases of the nasopharynx and its surrounding.
The recommended diagnostic strategy for mass lesions of the nasopharynx and surrounding structures is to use Gd-enhanced MRI as a primary study and contrast enhanced CT as a secondary study for the evaluation of fine bony details.
Summary and conclusion
The aim of this study is to assess the accuracy of magnetic resonance imaging versus computed tomography in diagnosis of nasopharyngeal mass.
This study was done during the period from June 2002 to December 2003 in Radiology Departments, Zagazig University Hospitals. The study included 30 patients, 19 males and 11 females, their ages ranged from 5 to 69 years.
The patients were subjected to:
1- Clinical examination.
2- CT scanning.
3- MRI
4- Histopathological analysis.
The lesions encountered in our study were classified into 22 malignant lesions and 8 of benign nature.
The malignant lesions were further subdivided into tumors arised from the nasopharynx itself, they were squamous cell carcinoma in 12 patients, lymphoma in 8 patients, and malignant tumors extended to the nasopharynx in the form of chordoma and carcinoma of the maxillary sinus.
Eight patients with benign lesions were included in our series, further subdivided into 6 cases arised from the nasopharynx, they were 3 cases of angiofibroma, 3 cases of adenoids, or direct extension from adjacent structures in two cases, one case of nasal angiofibroma and the other was pleomorphic adenoma of the deep part of the parotid gland.
Both CT and MRI were done for all our patients, CT was effective in the determination of the lesion, extension, other close association, the bone destruction and abnormal calcifications inside the tumor, however CT failed to distinguish between the tumor itself and the surrounding soft tissue structures.
