Abstract:
Pure cysts of the male genital system are rare, with the exception of epididymal cysts. Midline cystic masses in or near the prostate represent either an infectious etiology or utricular/Mullerian duct cysts. Prostatic diverticuli are extremely rare entities. A 61-year-old man presented with symptoms consistent with an active pelvic infection and computed tomography evidence of what was thought to be an intraprostatic abscess. Further studies revealed a large prostatic diverticulum and a poorly compliant bladder. The patient eventually required urinary diversion for symptom relief and upper urinary tract conservation.
Insights
Prostatic diverticuli, rare cystic masses near the prostate, can mimic infections. This case highlights a large diverticulum causing pelvic infection symptoms, necessitating urinary diversion for patient management.
Area of Science:
- Urology
- Radiology
- Surgical Pathology
Background:
- Pure cysts of the male genital system are uncommon, with epididymal cysts being a notable exception.
- Midline cystic masses in or near the prostate are typically associated with infectious causes or developmental remnants like utricular/Mullerian duct cysts.
- Prostatic diverticuli are exceptionally rare anatomical anomalies.

In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
