Abstract

F-Fluorodeoxyglucose-positron emission tomography/computed tomography (FDG PET/CT) has shown an increasing role in the evaluation of urinary bladder cancer, though benign pathological processes of the urinary bladder can also result in increased FDG uptake. Leiomyomas of urinary bladder are benign mesenchymal neoplasms and a very rare bladder tumor comprising <0.5% of all bladder tumors. Here, we present the low-grade FDG uptake in urinary bladder leiomyoma on PET/CT done for the clinical suspicion of bladder cancer, which can be a rare differential for bladder carcinoma.

摘要

氟代脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（FDG PET/CT）在膀胱癌评估中的作用日益凸显，不过膀胱的良性病理过程也可导致FDG摄取增加。膀胱平滑肌瘤是良性间叶性肿瘤，是一种非常罕见的膀胱肿瘤，占所有膀胱肿瘤的比例不到0.5%。在此，我们展示了因临床怀疑膀胱癌而行PET/CT检查时，膀胱平滑肌瘤呈现低级别FDG摄取，这可能是膀胱癌一种罕见的鉴别诊断情况。
