肾血管平滑肌脂肪瘤影像学诊断(附16例分析)

Imaging diagnosis of angioleiomyolipoma

目的 :探讨肾血管平滑肌脂肪瘤的CT、B超影像学表现特征。方法 :回顾分析经手术、病理证实的 16例肾血管平滑肌脂肪瘤CT、B超影像学表现及病理。结果 :本组 16例 ,其中单侧发病 11例 ,双侧发病 5例 ,合并结节硬化 2例。结论 :CT与B超综合影像诊断 ,可早期发现体积较小的肿块 ,CT能准确测定肿块内脂肪密度 ,其准确性明显优于B超检查。

Objective:To explore the imaging characteristics of CT and ultrasound of angioleiomyolipoma.[WT5”HZ]Methods:16 cases of CT and ultrasound manifestations of angioleiomyolipoma proved by operation and pathology were analyzed retrospectively .Results:11 of 16 occurred in single side,5 of 16 occurred in both sides, 2 of 16 cases accompanied with nodular sclerosis.Conclusion:CT and ultrasound comprehensive imaging diagnosis can find small volume mass in early stage, CT can measure the density of masses more exactly than ultrasound.
