Von Brunn cysts are formed by pinching off of epithelial nests from urothelial buds and rarely cause bladder outlet obstruction, with only 10 such cases reported in the literature. A young man presented with new-onset obstructive voiding symptoms. Cystoscopy confirmed the ultrasound and computed tomography findings of a midline cystic lesion at the bladder neck, above the prostate parenchyma, located anteriorly spanning from 11 to 1 o'clock. A possible ball valve effect of the cyst at the bladder neck was causing obstruction. Transurethral reroofing and cyst resection resulted in complete resolution of the voiding symptoms.
