A 50-year-old man presented with chest pain symptoms for 7 years. He did not report any other complaints. The diagnostic tests including physical examination, routine laboratory tests, chest x-ray, and electrocardiography were reported as normal. Cardiac MRI, however, revealed a 64 × 66 mm mass lesion in the left myocardium. He was referred to our unit for further tests. A PET/CT was carried out which demonstrated a minimally increased fluorodeoxyglucose uptake at the peripheral margins of the mass, which deemed to be suspicious for malignancy. The patient underwent a thoracotomy and the cardiac mass was excised. Histopathologic examination reported this lesion as a hydatid cyst.

Objective: To determine the frequency, localization and amount of thyroid remnant in extracapsular thyroidectomized patients. Methods:We postoperatively evaluated the thyroid bed of 38 totally thyroidectomized patients using thyroid scintigraphy, a thyroid uptake study and bilateral neck ultrasonography (US) to determine the extent of residual thyroid tissues. Results:In scintigraphic assessment, thyroid remnant was not seen in the thyroid bed in 13 cases, minimal thyroid remnant was detected in 15 cases, and visible uptake was seen in 10 cases. Ultrasonographic findings revealed the presence of remnant in 12 cases. However, US did not detect all remnant tissues diagnosed by TS. Conclusion:This study demonstrates that minimal thyroid remnant is left in the majority of cases, even after extracapsular total thyroidectomy, especially in the upper and middle zones.Key Words: Thyroid remnant, thyroid scintigraphy, thyroid uptake, ultrasonography, thyroidectomy Abstract Amaç: Ekstrakapsüler tiroidektomili hastalarda tiroid doku kalıntısının sıklığı, miktarı ve yerleşim yerini belirlemek.
