摘　　要：目的：探讨卵巢硬化性间质瘤（SST）的CT表现，以提高对该肿瘤的诊断水平。方法：回顾性分析经病理证实的12例卵巢SST患者的CT表现。结果：12例卵巢SST患者中，7例发生于左侧，5例发生于右侧。瘤体最大直径为3．6～12．1cm。CT平扫显示所有瘤体均表现为囊实混合性，其中以实性密度为主的10例（83％），以囊性密度为主的2例（17％）。4例（33％）可见钙化。增强扫描后不均匀明显强化，其表现为：按照强化范围，12例（100％）瘤体实性部分均表现为渐进性强化，似“肝海绵状血管瘤样”，而瘤体囊性部位始终无强化。按照强化程度分为两种类型：①早期快速一持续强化：7例（58％）病变实性部分强化呈“山峰型”．但囊性部分始终无强化。其中2例动脉期边缘可见明显强化的走行迂曲的粗大血管。②渐增性强化：5例（42％）病变实性部分强化呈“上升型”，但囊性部分始终无强化。其中2例病变呈多房状，可见不规则增厚的间隔及囊壁。结论：卵巢SSTCT表现具有一定特征性，CT检查结合临床表现有助于该疾病的诊断。Objective： To explore the CT imaging features of sclerosing stromal tumors （SST） of ovary, in order to improve diagnosis. Methods： CT manifestations of 12 cases with SST of ovary confitzned by pathology were analyzed retrospectively. Results： Among the 12 cases with SST of ovary, 7 of them located in the left ovary and 5 cases right. The tumors size var-ied from 3.6-12.1 cm in the largest diameter. Unenhanced CT scans showed mixed density mass with cystic and solid density, l0 cases （83%） were predominantly solid-density tumors, and 2 cases （17%） predominantly cystic-density tumor. Calcifications were seen in 4 cases （33%）. Contrast-enhanced CT scans showed heterogeneous enhancement significantly in all cases. The features were as follows： According to the range of enhancement： 12 cases （100%） solid components appeared as progressive enhancement, similar to ＂hepatic cavernous hemangioma＂, but the cystic components has no enhancement in the whole course. According to the mode of enhancement： ①Early-fast sustained enhancement： the curve of enhancement of the solid compo-nents in 7 cases（58%） appeared as peak-shape, but the cystic components has no enhancement in the whole course. Two cas-es showed dilated tortuous arteries enhanced obviously around the mass in the arterial phase. ②Gradual increase enhancement： In 5 cases（42%） the curve of enhancement of the solid components appeared as straight line shape, but the cystic components has no enhancement in the whole course. Two cases showed a muhiloculated cystic mass with irregularly thickened septae and tumor wall. Conclusion： SST of ovary has some specific CT manifestations, CT examination combined with clinical manifesta-tions is helpful for the diagnosis of SST of ovary.
