Angiomyolipoma is an uncommon lipomatous neoplasm of the liver, usually asymptomatic and identified incidentally. We describe the CT findings of a surgically confirmed case of spontaneously ruptured angiomyolipoma with evidence of internal hemorrhage and hemoperitoneum. The CT features were that of an exophitic, oval, well-defined mass with inhomogeneous attenuation values due to the presence of fat- and soft-tissue densities. A review of the literature identified 49 cases of hepatic angiomyolipoma. Few of these occurred in symptomatic patients and showed intratumoral hemorrhagic foci, but none had a clear rupture with external bleeding. To our knowledge, this is the first reported case with this complication.
血管平滑肌脂肪瘤是一种罕见的肝脏脂肪性肿瘤，通常无症状，多为偶然发现。我们描述了一例经手术证实的自发性破裂血管平滑肌脂肪瘤的CT表现，该病例有内部出血和血腹的证据。CT特征为突出于肝表面的椭圆形、边界清晰的肿块，由于存在脂肪和软组织密度，其衰减值不均匀。文献回顾发现49例肝血管平滑肌脂肪瘤。其中很少发生在有症状的患者中，且有瘤内出血灶，但均无明确的破裂及外部出血。据我们所知，这是首例报道有此并发症的病例。
