Abstract
Multislice CT has greatly improved the imaging capability of the nasopharynx because the clearest demonstration of the air soft tissue interfaces as well as the surrounding fascial planes, muscles and vessels in the parapharyngeal region. The ability of multislice CT with contrast enhancement to show neoplastic involvement of lymph nodes is increasing its use in staging neoplasms of the head and neck Nasopharyngeal tumours can spread to a large degree underneath normal appearing mucosa, so clinical assessment alone could not detect the deep extension which is best evaluated by multislice CT. Detailed assessment of tumours of the nasopharynx especially the malignant is essential to allow proper pretherapeutic staging and ensure appropriate therapy.
