目的：分析卵巢甲状腺肿(SO)的 CT 表现,提高对本病的认识和影像诊断水平。方法回顾性分析经手术病理证实的6例卵巢 SO 的 CT 图像,其中2例行增强扫描。结果6例 SO 均为单侧,CT 平扫表现分叶状、囊实性肿块,边界清晰；囊性部分为多个大小不等、边界清楚的囊腔,囊壁光滑、完整,4例可见高密度囊腔；实性部位于囊腔之间,呈形态不规则软组织密度；4例囊壁、间隔及实性部分可见条状、斑点状及弧形钙化；1例合并大量腹水。2例 CT 增强扫描：囊腔无强化,囊壁及实性部分轻度强化。结论SO CT 表现有一定特点,单发、边界清楚、囊实性肿块,有多个大小、密度不等囊腔,囊壁、间隔及实性部分钙化,实性部分显著强化,应该考虑到该病可能。

Objective To study the CT findings of struma ovarii(SO)and improve the understanding of SO imaging features. Methods CT images of 6 cases were retrospectively reviewed.CT plain scan was performed in 6 patients;CT enhancement scan was performed in 2 patients.Results All tumors were unilateral.On non-enhanced CT,the lesions presented as well-defined irregu-lar cystic-solid masses.The cystic portions presented as well-defined,multiple,various size,and there were entire cystic walls with smooth inner wall.Four tumors showed high attenuation lesions in the cyst portion of the mass on precontrast scans.The solid por-tions showed irregular tissue density,and were often distributed in the cysts.The tumors showed stippled calcification in solid por-tions and/or cystic wall in 4 cases.One tumor accompanied a great of ascites liquid.After contrast administration,the cystic por-tions showed no enhancement,and the cystic walls and the solid portions showed mild enhancement.Conclusion CT findings of SO have certain characteristics such as a cystic-solid and well-defined mass with calcification,high attenuation lesion on plain CT,and marked solid part enhancement on contrast CT.
