A Brunn’s cyst as a cause of bladder outlet obstruction: a case report

Abstract

A Brunn’s cyst in the proximity of the bladder neck is a rare cause of bladder outlet obstruction. This case study concerns a 45-year-old male presenting with bladder outlet obstruction secondary to a Brunn’s cyst. A provisional diagnosis of Brunn’s cyst was based on ultrasonography, CT scan and cystoscopic examination which indicated a cystic lesion at the bladder neck. Transurethral resection of the cyst was performed with successful resolution of the obstructive voiding symptoms. The final diagnosis of this case based on the pathology is a Brunn’s cyst.
