卵巢甲状腺瘤是一种在卵巢肿瘤内含有甲状腺组织的卵巢畸胎瘤。出现甲亢症状者仅5％～15％。约50％合并成熟囊性畸胎瘤,31％合并囊性腺瘤,单纯的卵巢甲状腺瘤约17％,术前诊断较困难,如能与卵巢癌鉴别,可避免手术范围过大。 作者研究13例经手术及病理确诊的卵巢甲状腺瘤,均行MRI,其中10例行CT扫描。 Ovarian thyroid tumor is a type of ovarian teratoma that contains thyroid tissue in ovarian tumors. Hyperthyroidism symptoms appear only 5% to 15%. About 50% with mature cystic teratoma, 31% with cystadenoma, simple ovarian thyroid tumor of about 17%, preoperative diagnosis is more difficult, if identified with ovarian cancer, to avoid the scope of the operation is too large. The authors studied 13 cases of ovarian thyroid tumors confirmed by surgery and pathology, were performed MRI, of which 10 cases underwent CT scan.
