肝血管平滑肌脂肪瘤是一种少见的来源于肝间叶组织的良性肿瘤,有人将其归于肝错构瘤,系血管、平滑肌纤维和脂肪组织错误地长入肝内所致。由于缺乏特异的声像图特征,术前确诊较为困难,现结合笔者遇到的一病例对其诊断和鉴别诊断作初步探讨。
Hepatic angiomyolipoma is a rare benign tumor originating from the interstitial tissue of the liver, which is attributed to hepatic hamartoma, which is caused by the erroneous growth of blood vessels, smooth muscle fibers and adipose tissue into the liver. Due to the lack of specific sonographic features, it is difficult to confirm the diagnosis before surgery. The diagnosis and differential diagnosis of the case encountered by the author are preliminary discussed.
