Ultrasound Evaluation of Thyroid Lesions

This study was done at Santhiram general hospital. 57 patients with thyroid swelling were examined with ultrasound and followed up with FNAC. Findings were analyzed which showed that 14 were cystic, 27 solid and 16 were mixed lesions; 93% of cystic lesions were benign (Table 2). Among solid lesions 83% were benign rest malignant. Among mixed lesions 87.75% benign and only 12.25% were malignant (Table 3). Ninty two per cent of goiter showed calicification papillary; carcinoma case showed calicification. Hypoechoic hallow showed 88% benign lesions and 12% of malignant lesions; hence US has a definete role in charecterising thyroid lesions. It is being cheap and readily available. The characterisation of perilesion halo is whether irregular or smooth which helps in differentiating benign and malignant nature of lesion. It helps in FNAC for exact localisation.
