腎血管筋脂肪腫の診断と治療について

Abstract

1) 34歳女, 2) 40歳女, じん血管筋脂肪しゅ2例.診断での超音波検査, CT scanの有用性と, 血尿に対するembolizationの止血効果についてのべた.超音波検査では, 脂肪組織は高レベルのエコー部分があり, 診断に非常に有用であるが, 高レベルエコーを示すじんがんの報告もあり, 超音波検査単独での診断はさけるべきで, そのさいCT scanが有用である.CT scanでは脂肪織はCT値で-20～-70を示すことが多く本症の診断が可能である.自験8例では, 両検査法を用いた最近の3例はいずれも本症を確実に診断している

We have hitherto reported 6 cases of renal angiomyolipoma. Recently, we encountered two more such cases. Case 1 is a 34-year-old woman with fever as the chief complaint. DIP revealed a tumor mass in the right upper pelvic pole. This mass showed a strong echo level on ECHO and adipose tissue of low density on CT scan. Therefore, the patient was diagnosed as having renal angiomyolipoma. Since liposarcoma was not ruled out by the examination of frozen sections during operation, nephrectomy was performed. Case 2 is a 40-year-old woman. Diagnosed as having bilateral renal angiomyolipoma, she underwent right nephrectomy 14 years ago. Two years ago, she had heavy hematuria, and had embolization of the left renal artery. She has had no bleeding since the embolization. We are of the view that ECHO and CT can are very useful for diagnosis of renal angiomyolipoma, and embolization for heavy hematuria, a complication, should be performed first of all.
