A case, is reported of a 40 year-old woman with a "form fruste" of tuberous sclerosis, multiple angiomyolipomas of the kidney, and an angiomyolipoma of the liver. On magnetic resonance imaging the hepatic mass was markedly hyperintense to liver on short TR/short TE spin-echo sequence. Spiral computed tomography during arterial portography showed hepatic mass in the right hemiliver with areas of negative attenuation values suggesting fat content. Pathologic examination of the resected specimen confirmed the diagnosis of an angiomyolipoma of the liver. Computed tomography during arterial portography is a commonly performed preoperative imaging modality. Therefore, recognition of angiomyolipoma of the liver by this technique is important, because this benign mesenchymal neoplasm may not require resection.
报道了一例40岁女性患者，患有结节性硬化症的“顿挫型”、多发性肾血管平滑肌脂肪瘤和肝血管平滑肌脂肪瘤。在磁共振成像中，肝脏肿块在短TR/短TE自旋回波序列上相对于肝脏呈明显高信号。动脉门静脉造影期间的螺旋计算机断层扫描显示右半肝有肝脏肿块，其衰减值为负的区域提示有脂肪成分。切除标本的病理检查证实为肝血管平滑肌脂肪瘤。动脉门静脉造影期间的计算机断层扫描是一种常用的术前成像方式。因此，通过该技术识别肝血管平滑肌脂肪瘤很重要，因为这种良性间叶性肿瘤可能不需要切除。
