Hepatic Angiomyolipoma: A Case Report

肝臟血管肌肉脂肪瘤:一病例報告

摘要


吾人報告一肝臟血管肌肉脂肪瘤病例之影像學上的表徵。在超音波上,一個界線明顯之高回音腫瘤被發現。磁振造影在T1影像表現為一低訊號腫瘤,並混雜有高訊號之小瘤在其中,而T2影像表現此腫瘤增加其訊號,但其中的小瘤則呈現低訊號影像。血管攝影則偽一高血管性腫瘤。病理學証實此一腫瘤包含成熟脂肪細胞,平滑肌細胞以及厚壁血管組織。

並列摘要


A case of hepatic angiomyolipoma and its imaging appearances are presented in this case report. On ultrasonography, a well defined hyperechoic tumor was disclosed. Magnetic resonance imaging revealed a hypointense mass mixed with hyperintense nodules within the tumor on T1- weighted image. On T2-weighted image, the tumor increased its signal intensity but the nodules became hypointense. A hypervascular tumor was demonstrated by angiography. Pathology study showed mature lipocytes, smooth muscle cells and thick-walled vessels in the tumor.
