ZINNERS SYNDROME A RARE PRESENTATION

Seminal vesicle cyst in association with ipsilateral renal agenesis was described by Zinner in 1914 and popularly known as Zinners syndrome. Most of them are asymptomatic. Usually they present in the second or third decade of life. We would like to present a case of Zinners syndrome. 21 year old male patient presented with dysuria and obstructive voiding symptoms of one year duration. On clinical evaluation the patient was found to be normal. Ultrasonogram revealed absent right kidney with a cyst protruding into right lateral wall and base of bladder. Intravenous urogram confirmed our finding. Contrast enhanced CT and TRUS confirmed our findings. Also we did a cystoscopy examination under local anesthesia which revealed a normal study except absent right hemitrigone. Since the patient was symptomatic we did a trans rectal ultrasound guided aspiration. On follow up the patient is symptom free. It is one of the rare genitourinary anomaly which we were able to manage by minimally invasive guided aspiration. Embryologically its due to abnormal mesonephric duct development resulting in ejaculatory duct atresia producing ipsilateral seminal vesicle cyst and ureteric bud anomaly causing ipsilateral renal agenesis.
