Congenital prostatic cysts: a case series

Prostatic cyst is a rare congenital disease which can be attributed to a number of etiologies, that mainly include cysts arising from mullerian ducts and utricle remnants, ejaculatory duct diverticulum, prostatic retention cyst and Zinner's Syndrome. Zinner’s Syndrome is a triad of mullerian ductabnormalities comprising of unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ejaculatory ductobstruction. It is often considered to be the male equivalent of Meyer RokitanskyKustner Hauser (MRKH) syndrome in females.
Transrectalultrasound (TRUS) has been proved to be a good imaging modality for diagnosing cysts as it has high accuracy, is cheap, easily available, quick and has no radiation risk while Magnetic Resonance Imaging (MRI) is more effective in assessing ejaculatory duct and seminal vesicles due to its high resolution. Upon evaluation by TRUS and MRI, surgical intervention can be further planned according to patient symptomatology.
In this case series we report three patients who presented to our outpatient department on three different occasions. Two of these patients were diagnosed with Zinner’s Syndrome and one patient was diagnosed with a midline prostatic cyst.
