Abstract

Bladder leiomyomas are rare neoplasms and various diagnostic methods are available to assist in confirming diagnosis preoperatively. Presented here is a case of bladder leiomyoma in a 41-year-old female who presented with urinary symptoms and right thigh pain. Imaging revealed a soft tissue density mass in the bladder wall. However concerns of a leiomyosarcoma remained. An 18F-fluorodeoxyglucose (FDG) positron emission tomography/computerized tomography (PET/CT) demonstrated low FDG uptake and absence of metastatic lesions. In combination with operative findings, the tumor allowed for localized resection instead of more invasive partial cystectomy. Therefore, FDG-PET might be used to support the diagnosis of leiomyoma and potentially facilitate a less aggressive surgical management.

膀胱平滑肌瘤与18F氟脱氧葡萄糖正电子发射断层扫描的应用——一例报告
膀胱平滑肌瘤是一种罕见的肿瘤,各种诊断方法可用于术前诊断。本文报告一位41岁女性的膀胱平滑肌瘤,其表现为泌尿系统症状和右大腿疼痛。影像显示膀胱壁有软组织密度肿块。然而,对平滑肌肉瘤的担忧仍然存在。18F-氟脱氧葡萄糖(FDG)正电子发射断层扫描/计算机断层扫描(PET/CT)显示FDG摄取低且无转移性病变。结合手术结果,肿瘤可以进行局部切除,而不是更具侵袭性的部分膀胱切除术。因此,FDG-PET可能用于支持平滑肌瘤的诊断,并有可能促进不那么积极的手术治疗。
