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3.6~12.1 cm。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-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SST CT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。

Abstract

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 confirmed 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 varied from 3.6～12.1 cm in the largest diameter. Unenhanced CT scans showed mixed density mass with cystic and solid density, 10 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 components in 7 cases(58%) appeared as peak-shape, but the cystic components has no enhancement in the whole course. Two cases 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 multiloculated cystic mass with irregularly thickened septae and tumor wall. Conclusion: SST of ovary has some specific CT manifestations, CT examination combined with clinical manifestations is helpful for the diagnosis of SST of ovary.
