子宫、子宫阔韧带脂肪性肿瘤的影像学诊断

Imaging Diagnosis of Lipomatous Tumors of the Uterus or Broad Ligament

子宫、子宫阔韧带脂肪类肿瘤非常少见。作者报告手术病理证实的３例子宫平滑肌脂肪瘤、２例子宫阔韧带血管平滑肌脂肪瘤影像学表现。肿瘤内的脂肪成份在影像上有特征性，Ｂ超扫描表现为高回声伴有声衰减区；ＣＴ扫描呈脂肪密度区。肿瘤位于子宫内时易于诊断；肿瘤位于子宫浆膜下或子宫阔韧带内时易被误诊为卵巢囊性畸胎瘤；肿瘤以平滑肌成份为主时不易与子宫平滑肌瘤鉴别。

Five cases of lipomatous tumor of the uterus or broad ligament are presented with uterine lipomyoma, 3 and broad ligament angiomyolipoma, 2. The fatty component in the mass was characteristic in imaging diagnosis, and was shown as fat density at CT scan and hyperechogenity with posterior attenuation at ultrasonography.Tumor located in submucosa or myometrium could relatively be easy to diagnose,those located in subserosa or broad ligament are liable to be confused with ovarian teratomas by imaging diagnosis,Tumor with predominant leiomyomatous element might have the similar imaging finding to uterine leiomyoma and could be difficult in differentiation.
