Midline prostatic cyst

Case contributed by Dr Mostafa El-Feky


Hematuria, UTI, irritative symptoms.

Patient Data

Age: 27
Gender: Male

Ultrasound of the urinary tract

Patient is scanned with full bladder.

A well defined cystic lesion is noted in the posterior lobe of the prostate with anechoic content, thin imperceptible wall.

Case Discussion

This likely represents a simple prostatic cyst, which can be a Mullerian duct cyst or utricle cyst

Mullerian duct cysts can arise anywhere along the path of Mullerian duct regression, from scrotum to utricle (c.f. prostatic utricle cysts always arise from the level of the verumontanum and are always in the midline). They do not communicate with the urethra.

Mullerian duct cysts typically extend above the prostate gland (utricle cysts are variable in size but are usually smaller than mullenian duct cysts and usually do not extend above the prostate gland).

Mullerian duct cysts are not associated with other abnormalities (utricle cysts are associated with a variety of genitourinary abnormalities).
