Description
Summary:Background Correlation of cytologic and ultrasound findings is extremely valuable for the cytopathologist in management of thyroid nodules. Methods Ultrasound scans (US) of all thyroid FNA taken over a 13 month period and reported by a single cytologist were reviewed at the time of reporting, focusing on aspirates that were non‐diagnostic/unsatisfactory, equivalent to Bethesda Class I, UK Royal College of Pathologists Class Thy1 or Thy1c. Results FNA cases [68 (40.7%)] were classified as Thy1, equivalent to Bethesda Class I. US of 3 Thy1 cases were not available for review. On cytologist US review 9 cases were classified as pure cystic, 28 as mixed cystic/solid, 12 as predominantly solid/focally cystic and 16 as purely solid. 27 (41.5%) of cases on cytological assessment were Thy1 and showed no evidence of a cyst on US, 17 (26.1%) were Thy1/Thy1c showing features suggestive of a possible cyst and 21 (32.3%) were Thy1c showing definite features of a cyst. Fifteen of 16 (93.7%) of pure solid cases on US were Thy1, equivalent to Bethesda Class I and all 9 (100%) of cases that were pure cystic on US were reported as Thy1c—equivalent to Bethesda Category I—cyst fluid only (P
