Hepatic angiomyolipomas (AMLs) are typically benign tumors containing varying amounts of smooth muscle cells, adipose tissue, and vessels, and are commonly found in the kidney and occasionally in the liver. The preoperative diagnosis of hepatic AML is primarily made from imaging and fine-needle aspiration biopsy results, though limited experience for such diagnoses can result in misdiagnosis. Some uncommon features of hepatic AML have been reported in the literature without an objective or qualitative consensus. As the majority of cases are benign, conservative treatment of AMLs is recommended. However, in rare cases, liver transplantation has been implemented. Only five cases of malignant hepatic AML have been reported. We report a rare case of recurrent posthepatectomy malignant hepatic AML that was misdiagnosed as liver cancer in a 37-year-old woman, which was treated by liver transplantation. The imaging and pathologic findings are presented in order to provide a more concise description to aid in future diagnoses.
肝脏血管平滑肌脂肪瘤（AMLs）是一种典型的良性肿瘤，由不同数量的平滑肌细胞、脂肪组织和血管构成，常见于肾脏，偶尔也见于肝脏。肝脏AML的术前诊断主要依据影像学检查和细针穿刺活检结果，但由于此类诊断经验有限，可能会导致误诊。文献中报道了一些肝脏AML的罕见特征，但尚未达成客观或定性的共识。由于大多数病例为良性，建议对AMLs进行保守治疗。然而，在罕见情况下，也会实施肝移植。目前仅报道了5例恶性肝脏AML。我们报告了一例罕见的复发性肝切除术后恶性肝脏AML病例，该病例发生在一名37岁女性身上，术前被误诊为肝癌，最终接受了肝移植治疗。本文展示了其影像学和病理学检查结果，以便提供更简洁的描述，辅助未来的诊断。
