Clinical Profile of Patients with Thyroid Nodules Subjected for Ultrasonography

Abstract

Background: Hashimoto's thyroiditis cannot be distinguished from those of multinodular goitre (MNG). Basically the thyroid is enlarged bilaterally with an uneven parenchymal pattern mainly showing decrease in the normal echogenicity. The ultrasound appearance of Hashimoto's thytoiditis is that of a diffuse glandular enlargement with irregular lobulated margins. There is a generalised decrease in parenchymal reflectivity with a typical lobulated pattern due to highly reflective fibrous bands which separate the echo poor areas. Subjects and Methods: Based on the inclusion and exclusion criteria, 80 cases of thyroid lesions diagnosed by ultrasound were included in the study. The ultrasonography and ultrasound elastography examination was done in the department of Radiology .These 80 cases which were found to have thyroid lesion on ultrasound were subjected to FNAC for confirmation of ultrasound finding and establishment of final diagnosis. Results: Study showed no vascularity (TYPE1) and (TYPE2) peripheral vascularity in 100% of benign nodules, none of the malignant nodules showed type 1 and 2 vascularity. 95.2% of benign nodules showed TYPE 3 vascularity and 4.76% of cases were malignant. Conclusion: 40% of the benign nodules showed intra nodular vascularity (TYPE4) and 60% of the cases were malignant.
