摘要
腎臟血管肌脂肪瘤又名腎過誤腫，是因腎臟裏成分的不正常混合而成，腫瘤內主要含有動脈血管瘤；平滑肌及脂肪組織，是一良性瘤。本文複閱8個病例，年齡自25至57歲；4例女性，4例男性；其中祇有一例33歲女性病人合併結節性硬化。一般在臨床及X光上大都表現其：1.可觸摸到慢慢變大的腹部腫塊，脇腹部疼痛，慢性出血及貧血等象；2.靜脈注射腎盂X光攝影中，可見腎臟有空間占據病灶；3.薄層斷面X光攝影，常可見病灶中有X光線透性脂肪濃度；腎臟血管X光攝影可見含血管豐富的腫瘤及大小不等的動脈血管瘤。腎過誤腫之圖像因成份比例不同而異。電腦斷層攝影的應用容易測知腫瘤中有無脂肪的存在，而對此病的正確診斷有相當助益。

Eight proved cases of renal angiomyolipoma were encountered in the Department of Radiology of Veteran General Hospital. There were 4 males and 4 females, age ranged from 25 to 57 years old, four of them had bilateral renal involvement, and one case showed evidence of tuberous sclerosis. General clinical conditions and roentgenological criteria of renal angiomyolipoma were as follows: 1. Palpable growing abdominal mass, flank pain, chronic bleeding and aneima. 2. IV Urography showed space-occupying lesion in the involved kidney. 3. Nephrotomogram showed radiolucent lipid density within the tumor. 4. Renal angiogram revealed abundant dilated tortuous blood vessels associated with different sized aneurysms. 5. Computed tomography scan can easily detect lipid density within the tumor mass, it should be performed in cases when differential diagnosis is difficult. Without the help of the C-T scan, it is unable to differentiate renal angiomyolipoma from: renal cell carcinoma, polycystic kidney disease, retroperitoneal tumor or liposarcoma or lipomatosis.
