肾血管平滑肌脂肪瘤的CT诊断与治疗(附35例分析)

CT diagnosis and clinical treatmnet of renal angiolipoleiomyoma(analysis of 35 cases)

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。方法:分析35例肾血管平滑肌脂肪瘤的CT表现,并与29例手术病理结果对照。结果:肾血管平滑肌脂肪瘤患者多见于女性,外向性肾血管平滑肌脂肪瘤病灶较大,直径大于3cm,肿瘤出血及自发性破裂是本病最常见的严重并发症,23例多脂肪及少脂肪肾血管平滑肌脂肪瘤CT可作出诊断,脂肪成分很少或无脂肪的肾血管平滑肌脂肪瘤应结合B超、MRI诊断。结论:CT对肾血管平滑肌脂肪瘤及瘤内出血、自发性肾破裂多能作出明确诊断,对确定治疗方案有一定的指导作用。

Objective： To evaluate CT in the diagnosis of renal angiolipoleiomyoma （ALL）, and to study the selection of the treatment. Methods： CT findings in 35 patients with renal ALL were retrospectively analyzed and compared with the pathological results of 29 cases. Results： AU cases had a predilection for female. Exophytic growing ALL was usually large,with the diameter over 3cm. 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 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.
