Introduction: Bladder outlet obstruction in younger men is often secondary to urethral stricture disease. In the older population it is often a result of benign prostatic hypertrophy. Materials and Methods: We describe the diagnosis, treatment, and outcome of a rare case of a Brunn's cyst causing bladder outlet obstruction in a 43-year-old male who was evaluated for obstructive urinary complaints. Results: Ultrasound and cystoscopy revealed a cystic lesion at the bladder neck. Transurethral unroofing of the cyst resulted in resolution of the obstructive symptoms and resumption of normal voiding. Final pathology revealed a cystic structure with predominately denuded urothelium with multiple submucosal cystically dilated von Brunn's nests, most consistent with a Brunn's cyst. A search of the literate reveals only one similar case. Conclusions: We present the rare case of a Brunn's cyst causing bladder outlet obstruction in a young man.
