Abstract :

Ultrasound-guided fine needle aspiration (US-FNA) has become a first diagnostic modality and a gold standard for evaluation of thyroid nodules and thyroid has become the most popular site for FNA. Recently, cytopathologists started to show interest in performing US-FNA themselves. In addition to special training in performing FNA under the US-guidance, familiarity with US features of various thyroid lesions is essential. In addition, up to 15% of thyroid FNAs were reported indeterminate. One way to reduce the â�?�?indeterminateâ�? rate is to use team approach and to gain the knowledge of thyroid ultrasound by correlating ultrasound with the final cytologic findings with follow-up surgical pathology including gross pathology and histologic findings of aspirated lesion. Knowing the gross and histopathologic basis of thyroid ultrasound will be tremendously helpful in cytologic interpretation and in minimizing the indeterminate and non-diagnostic rates in thyroid cytology. The presenter has been doing on-site assessment of >100,000 US-FNA of thyroid and would like to share her collection of ultrasound, Doppler, FNA cytology, gross image of resected tumors and histology ranging from scanning to high magnifications. Cases selected for this presentation are adenomatoid nodule, follicular adenoma, follicular adenoma with cystic degeneration, angio invasive follicular carcinoma, follicular variant of papillary carcinoma, encapsulated follicular variant of papillary carcinoma, Hurthle cell adenoma with post-FNA infarction, Hurthle cell carcinoma, classic papillary carcinoma with psammoma bodies, cystic papillary carcinoma, hobnail variant of papillary carcinoma, tall cell variant of papillary carcinoma and poorly differentiated thyroid carcinoma.
