摘要：肝血管平滑肌脂肪瘤（HAML）是一種罕見的良性間充質(zhì)腫瘤，多發(fā)于中年女性，由于早期無明顯癥狀，且缺乏特異的影像學表現(xiàn)，因此，診斷難度大，誤診率高。本文報道1例巨型HAML伴包膜下破裂誤診為肝細胞癌的病例，介紹其病例特點和診治經(jīng)過，期望為此類疾病的診治提供參考。

Abstract：Hepatic angiomyolipoma （HAML） is a rare benign mesenchymal tumor frequently observed in middle-aged women. Due to the absence of prominent symptoms in the early stage and the lack of specific imaging findings，the diagnosis of this disease can be challenging，leading to a high rate of misdiagnosis. This article reports a case of giant HAML with subcapsular rupture that was misdiagnosed as hepatocellular carcinoma and introduces the characteristics of the case and its diagnosis and treatment process，in order to provide a reference for the diagnosis and treatment of this type of disease.
