Severe lower urinary tract symptoms due to anteriorly located midline prostatic cyst arising from the bladder neck in a young male: case report

Anteriorly Placed Midline Intraprostatic Cyst Resulting in Bothersome Lower Urinary Tract Symptoms: A Case Report

Prostatic cysts are rare, usually asymptomatic and detected incidentally at imaging. Midline prostatic cysts are less common and mostly located posteriorly. We describe a case of a 51-year-old man with unknown comorbidities who presented with troublesome irritative and voiding symptoms. Transabdominal and transrectal ultrasound, abdominal computed tomography and pelvic magnetic resonance imaging revealed a midline intraprostatic cyst protruding into the bladder lumen, with no communication with the urethra on voiding cystourethrography. Uroflowmetry findings suggested an obstructed flow. The patient underwent transurethral marsupialization of the cyst, which was found to project on the bladder outlet causing urinary obstruction, with excellent outcomes. What makes this case further interesting is the unusual cyst’s relationship with the patient’s prostate and bladder neck. To our best knowledge, this is so far the seventh reported case in the literature to describe an anteriorly placed midline intraprostatic cyst projecting at the bladder neck region and causing bothersome lower urinary tract symptoms.
