Huge and Multifocal Medullary Thyroid Carcinoma with Postoperative Residual and Recurrent Lesions Demonstrated by Serial Thallium-201 Scans: A Case Report

　　　　　本病例報告一名45歲男性罹患甲狀腺體質癌，手術前後以201Tl掃描連續追蹤的重要性。在一系列4次的201Tl掃描中清楚的顯示出術前病灶的範圍與位置，術後病灶的殘餘組織，及在接受sandostatin和放射治療後的病灶復發等。文中並討論201T1掃描在甲狀腺髓質癌術後立即偵測殘餘腫瘤組織及其他角色之應用。
　　　　　A 45 year-old male medullary thyroid carcinoma (MTC) patient is presented to demonstrate the importance and usefulness of serial thallium-201 (201TI) scans before and after operation. Four serial 201TI scans clearly showed the location and extension of the tumor before the operation, the residual tumor soon after the opera-dion, and the progression of the tumor even under san-dostatin therapy and radiotherapy. The roles of 201TI scan in MTC and a residual tumor which was found soon after operation are of interests.
