✦ Synopsis

BACKGROUND. Ultrasound (US) has been shown to be a sensitive technique for monitoring patients for recurrent thyroid carcinoma in the thyroid bed after total thyroidectomy. However, the role of US-guided fine-needle aspiration biopsy (FNAB) in the confirmation of sonographically indeterminate or suspicious masses has not been adequately addressed. The purposes of this study were to determine the sensitivity and specificity of US-guided FNAB of the thyroid bed for diagnosing recurrent carcinoma after total thyroidectomy and to highlight potential diagnostic pitfalls.

METHODS.

Twenty-one patients with a history of total thyroidectomy and histologically confirmed thyroid carcinoma who had undergone US-guided FNAB of hypoechoic lesions in the thyroid bed were included in this retrospective study.

Fifteen of the 21 had papillary carcinoma (PC), 5 had medullary carcinoma (MC), and 1 had Hu ¨rthle cell carcinoma (HTC). The cytologic features of the aspirates were compared with histopathologic findings of pre-and post-FNA surgery. Immunohistochemical staining for thyroglobulin, calcitonin, and parathyroid hormone was performed in four cases.
