| 目的 分析卵巢甲状腺肿(SO)的CT表现特点。方法 回顾性分析经手术病理证实的9例卵巢甲状腺肿的CT表现,并与病理所见作对照分析。结果 9例SO均为单侧附件肿块,呈椭圆形或分叶状,边界清楚;3例呈囊性,6例为囊性为主的囊实性;囊内密度不均匀,其中5例呈高密度。增强后实质部分多中等(3例)或显著强化(5例)。6例伴有斑点、线条及环形钙化;4例少量腹水。镜下见肿瘤由甲状腺滤泡样结构和富含血管及纤维组织的基质组成,滤泡大小不等,滤泡腔内充满嗜伊红高蛋白凝胶样物质。结论 边界清楚的囊实性肿块、钙化及囊内平扫高密度、实质部分显著强化是SO的CT表现特点。 |

| Objective To observe CT features of struma ovarii (SO) in comparison of pathologic findings. Methods CT features of 9 patients with pathologically confirmed SO were analyzed retrospectively and compared with pathological findings. Results All tumors were unilateral and had smooth margins, 3 were cystic and 6 were cystic-solid lesions, 5 were high attenuation lesions in the cyst portion of the mass on contrast CT. The cyst wall moderately (n=3) or markedly (n=5) enhanced after administration of contrast medium. Scattered, stripe-like or ring-like calcifications were found in 6 patients. On pathology, most of cystic portions were filled with high proteinaceous gelatinous fluid of eosinophiclic colloid, and the solid portion of tumors consisted of the thyroid tissue and stoma containing abundant blood vessels and fibrous tissue. Conclusion SO appears as a smooth marginated multicystic mass with calcification, high attenuation lesionin plain CT, and marked solid part enhancement on contrast CT. |
