Introduction:

Bladder paraganglioma are extremely rare. Only 6% of extraadrenal paragangliomas occurred in the urinary bladder. Most of the bladder paragangliomas may cause hypertension, headache, flush and painless hematuria. We presented a 72-year-old man with bladder paraganglioma found incidentally, and was managed by transurethral resection.  

Case presentation: 

A 72-year-old man had past history of hypertension and hyperuricemia under medication control. He suffered from left flank pain for one week and the renal sonography revealed left hydronephrosis. The abdominal computer tomography was arranged and one 0.7cm lesion at anterior aspect of urinary bladder was found incidentally. The patient accepted the cystoscopic examination under general anesthesia and a 1.5 cm well-defined, smooth surface bladder mass over anterior bladder wall was found. The bladder mass was completely resected endoscopically. The pathological diagnosis was consistent with bladder paraganglioma. The patient felt hematuria improved, and the repeated cystoscopy showed no recurrent of bladder tumor.

 

Conclusion:

        Paraganglioma of the urinary bladder is a rare condition. It could cause functional and symptomatic problem. Operation management is the mainstay treatment, transurethral resection, partial cystectomy or radical cystectomy should be considered in the different kinds of tumor size or invasive layer. Lifelong follow up should be considered for the high recurrence rate.
