Abstract
T
his study was conducted on 50 patients with thyroid nodules detected by clinical palpation or incidentally noted during neck imaging for other reasons. There were 33females (74%) and 17 males (26%). Their ages ranged from 41 to 50 years.
TIRADS is a newly developing term, first descried by Horvath et al. in 2017; however this system was difficult to use in clinical practice. Tessler et al. proposed a newer system in 2020; after that Skowrońska et al. in 2018 added their system which was further modified by those who use it.
Modified Russ TIRADS is an easy system to use and remember in clinical practice.
The aim of this work was to improve the management of the patients and to reduce cost-effectiveness by decreasing number of unnecessary fine needle aspiration cytology (FNAC).
All patients in the study were subjected to full history taking, thorough clinical examination. Gray scale Ultrasound and color Doppler examination were done to all patients. The nodules were classified into TIRADS categories and the risk of malignancy was calculated for each category.
Malignant nodules were found in TIRADS 4a, 4b and 5; these categories are considered as suspicious of malignancy. Nodules in categories 2 and 3 were all benign in our study.
The major ultrasound features seen associated with malignancy were microcalcifications, taller than wider shape of the nodule, hypoechoic and marked hypoechoic echopattern of the nodule, irregular borders and presence of suspicious cervical lymph nodes.
