卵巢甲状腺肿(struma ovarii,SO)起源于卵巢的生殖细胞,是指肿瘤全部由甲状腺组织构成或肿瘤中甲状腺组织占50%以上[1]。目前对该病的认识较局限,而且该病的临床表现缺乏特异性,易被误诊为卵巢癌,确诊需术后组织病理学检查。笔者报道了1例SO伴腹膜转移患者的18F-FDG PET/CT 显像结果,结合其临床资料及影像学检查,并复习相关文献,分析其误诊原因,从而提高影像医师对该病诊断的准确率。

摘要: 卵巢甲状腺肿是一种罕见的卵巢肿瘤,肿瘤全部由甲状腺组织构成,或甲状腺组织占全部肿瘤的50%以上。笔者报道了1例因持续性腹胀就诊的卵巢甲状腺肿伴腹膜转移患者,根据患者的临床表现、实验室检查及影像学表现分析该病例的特点,并结合相关文献进一步复习卵巢甲状腺肿的影像表现及误诊原因,从而为临床提供早期诊断依据。Abstract: Struma ovarii is a rare disease in which the tumor is composed entirely of thyroid tissue, or thyroid tissue accounts for more than 50% of the total tumor. The author reported a case of a patient with struma ovarii with peritoneal metastasis who received medical treatment due to persistent abdominal distension. The characteristics of the case were analyzed according to the clinical manifestations, laboratory examination and imaging findings of the patient. Combined with relevant literatures, the imaging manifestations and causes of misdiagnosis of struma ovarii were further reviewed, so as to provide clinical basis for early diagnosis.
