肾血管平滑肌脂肪瘤的CT表现及治疗

目的 评价肾血管平滑肌脂肪瘤（angiolipoleiomyoma,ALL）的CT诊断价值及治疗方法。材料与方法 回顾性分析25例ALL的CT表现，并与19例手术病理结果对照。结果 ALL多见于女性。外向性ALL（周边型肿瘤）病灶较大，直径大于4cm。肿瘤出血及自发性是肾存裂是本病最常见的严重并发症，23例多脂肪及少脂肪ALL CT可作出诊断,诚分很少或无脂肪的ALL应结合B超、MRI诊断。结论 CT对ALL及瘤内出血、自发性肾破裂多能作出明确诊断，对确定治疗方式有指导作用。少或无脂肪成分ALL B超、MRI检查较敏感。

CT Diagnosis and Clinical Treatment of Renal Angiolipoleiomyoma

Objective To evaluate CT in the diagnosis of renal angiolipoleiomyoma (ALL), and to study the selection of the treatment.Materials and Methods CT findings in 25 patients with renal ALL were retrospectively analyzed and compared with the pathological results of 19 cases.Results All had a predilection for female. Exophytic growing ALL was usually large, with the diameter over 4cm. Internal bleeding and rupture of the kidney were the most common complications. CT could diagnose ALL which had certain, much or less, adipose tissue. For the diagnosis of those ALL which had little adipose tissue, a combination with the aid of ultrasonography and/or MRI was necessary. Surgical remove was the main treatment.Conclusion CT is helpful for the diagnosis of ALL, its internal bleeding and rupture of the kidney, and can provide information guiding the therapy. Ultrasonography and MRI are sensitive in detecting ALL having little adipose tissue. Normal renal tissue should be reserved as much as possible during operation.
