CORRELATION BETWEEN USG AND FNAC IN THYROID SWELLING
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 16
Abstract
BACKGROUND Nodular disease of the thyroid is very common, while cancer is less common. A definite diagnosis of either is difficult to make. The general prevalence of thyroid nodules is very high. They are detectable in 5% of the normal population on clinical examination, in over 48% on high-resolution ultrasound, and in over 50% at autopsy. Aims and Objectives- The purpose of the study was to evaluate clinically the thyroid swelling by sonography and FNAC in various disorders of thyroid gland with histopathological correlation. MATERIALS AND METHODS The present descriptive diagnostic study included 100 patients with clinically palpable thyroid swelling. The patients included in the study were subjected to gray scale and colour Doppler examination of the thyroid gland and fine needle aspiration cytology and histopathological examination. RESULTS Among the 100 patients examined, 30 patients had malignant lesions and 70 patients had benign lesions on final histopathology. All the diagnosis made by ultrasound was compared with FNAC reports. The characteristics of malignant lesions on ultrasonography included single ill-defined microcalcifications, lymphadenopathy and solid predominantly hypoechoic nodule. CONCLUSION Ultrasonography is valuable for identifying many malignant or potentially malignant thyroid nodules. Although, there is some overlap between the ultrasonography appearance of benign nodules and that of malignant nodules, certain ultrasonography features are helpful in differentiating between the two. FNAC can itself diagnose benign conditions and can also be helpful as an aid to ultrasonography features to suggest malignancy, even though it can report malignancy of follicular variety.
