Leiomyoma of the Urinary Bladder：A Case Report

膀胱平滑肌瘤是非常罕見的，佔膀胱良性間葉的腫瘤的35%。本文報告一膀胱平滑肌瘤病例。一位32歲女性因不孕求診，經腹部超音波檢查意外發現一不正常的膀胱腫塊：由理學檢查發現接近右側膀胱頸處可摸到一腫塊：膀胱鏡檢於膀胱右側壁看到一覆蓋正常膀胱黏膜的外側壓迫腫塊。電腦斷層顯示在膀胱右側壁有一質地均勻的腫瘤而且沒有合併腫大的淋巴結。核磁共振掃瞄發現在膀胱的右側有一管腔內的圓形腫瘤，疑似壁內的神經的或間葉的腫瘤。經手術切除，病理診斷為膀胱平滑肌瘤。內文中討論膀胱平滑肌瘤的診斷及處置並對文獻作一簡單回顧。

Leiomyoma of the urinary bladder is a rare tumor and constitutes 35% of benign mesenchymal bladder tumors. Herein, we report a case of leiomyoma of the bladder. A 32-year-old female was incidentally found to have an abnormal bladder mass on abdominal ultrasound during work-up for infertility. Bimanual examination then revealed a mass on the right side near the bladder neck area. On cystoscopic examination, an external compression mass covered with normal bladder mucosa could be seen at the right lateral wall. Computerized tomography revealed a homogeneous solitary tumor protruding into the urinary bladder from the right lateral wall without enlarged lymph nodes. Magnetic resonance imaging showed an intraluminal round mass at the right aspect of the urinary bladder, leading to suspicion of an intramural neurogenic or mesenchymal tumor. Surgical exploration was performed via a lower midline incision and a 5.0 x 4.5 x 2.2 cm mass was excised. The pathologic diagnosis was leiomyoma of the bladder. We discuss the diagnosis and management of leiomyoma of the bladder and briefly review the literature.
