膀胱之亞神經節瘤是一種相當罕見的膀胱腫瘤，其臨床表現、惡性轉變之預測至今仍無一明確之方法，故患者需要被長期的追蹤。本文報告一位32歲男性因無痛性血尿及解尿時伴隨心悸和頭痛，至本院泌尿科求診。由腫部超音波檢查在膀胱右外側壁發現一突出並有血塊的覆蓋的腫瘤，由於腫瘤和膀胱壁組織交錯混合生長，所以經由尿道至膀胱內視鏡無法將腫瘤完全切除。在術後3星期的放射性碘131追蹤發現膀胱仍有殘存之腫瘤存在。腫瘤之組織病理檢查結果為罕見之膀胱亞神經節癌。本文除病倒報告同時也回顧並比較相關之文獻。

Paragangliomas of the urinary bladder are very rare. To date, there are no reliable methods for predicting their clinical behavior, so long-term follow-up is required. We describe a paraganglioma of the urinary bladder in a 32-year-old male who presented with painless gross hematuria. Abdominal ultrasonography revealed a protruding mass with hematoma over the right lateral wall of the urinary bladder. The tumor was not completely resected by transurethral resection of bladder tumor (TURBT) due to intermingling with the bladder wall. Follow-up I131-metaiodobenzylguanidine was performed 3 weeks after surgery and suspected incomplete resection lesions were noted. Histologic examination of the tumor indicated paraganglioma of the urinary bladder. We also provide a brief review of the literature for comparison.
