Abstract：
A 41-year-old man was diagnosed with a huge symptomatic liver mass and was referred to our hospital for liver biopsy and further evaluation. He presented with right upper quadrant tenderness. Enhanced abdominal computed tomography and magnetic resonance imaging revealed a 12.5-cm relatively well-defined heterogeneous enhancing mass in the right inferior liver with a large exophytic component containing a fat component and progressive delayed enhancement. The patient underwent right inferior sectionectomy. The pathological diagnosis was confirmed as angiomyolipoma, 12.3×9.2×5.0 cm in size, with tumor necrosis in 20% of the tissue. Hepatic angiomyolipoma is known as a benign tumor, but in our case, because of the large tumor size and coagulative necrosis, this tumor had malignant potential; surgical resection was deemed to be appropriate, and close follow-up monitoring was essential postoperatively.
摘要：
一名41岁的男子被诊断出患有巨大的症状性肝肿块，并被转诊到我们医院进行肝活检和进一步评估。他表现出右上腹压痛。增强的腹部计算机断层扫描和磁共振成像显示，右下肝中有12.5厘米相对明确的异质增强肿块，其中含有脂肪成分的大量外生成分和进行性延迟增强。患者接受了右下部分切除术。病理诊断为血管平滑肌脂肪瘤，12.3×9.2×5.0厘米,20%的组织有肿瘤坏死。肝血管平滑肌脂肪瘤被称为良性肿瘤，但在我们的案例中,因为肿瘤体积大和凝固性坏死,该肿瘤具有恶性潜能；手术切除被认为是合适的，术后密切随访监测至关重要。
