Paraganglioma of the urinary bladder is a very rare disease accounting for 0.06% of all bladder tumors. Owing to their rarity and symptomatic variability, preoperative diagnosis is often difficult.
A 70-year-old male was referred to our department for hematuria. Cystoscopy showed a non-papillary broad-based tumor. Computed tomography and magnetic resonance imaging revealed a 32-mm bladder tumor at the top of the bladder, which suggested muscle-invasive bladder tumor. We diagnosed muscle-invasive bladder cancer or urachal carcinoma, and transurethral resection of the bladder tumor was performed. At the initiation of transurethral resection of the bladder tumor, the systolic blood pressure was elevated to over 200 mmHg. The pathological findings revealed paraganglioma of the urinary bladder, and afterward, a partial cystectomy was performed.
We herein reported the case of paraganglioma in the bladder whose blood pressure became extremely elevated during transurethral resection of the bladder tumor. In addition, we analyzed important factors for preoperative diagnosis using 162 cases reported in Japan.
膀胱副神经节瘤是一种非常罕见的疾病，占所有膀胱肿瘤的0.06%。由于其罕见性和症状的变异性，术前诊断往往很困难。
一名70岁男性因血尿转诊至我科。膀胱镜检查显示一个无蒂的广基肿瘤。计算机断层扫描和磁共振成像显示膀胱顶部有一个32毫米的膀胱肿瘤，提示肌层浸润性膀胱肿瘤。我们诊断为肌层浸润性膀胱癌或脐尿管癌，并进行了经尿道膀胱肿瘤切除术。在经尿道膀胱肿瘤切除术开始时，收缩压升高至200 mmHg以上。病理结果显示为膀胱副神经节瘤，随后进行了部分膀胱切除术。
我们在此报告了一例膀胱副神经节瘤病例，其在经尿道膀胱肿瘤切除术中血压极度升高。此外，我们利用日本报道的162例病例分析了术前诊断的重要因素。
