Acute urinary retention due to a prostatic cystadenoma. Case report.

INTRODUCTION Papillary cystadenoma of the prostate is a rare benign tumor that affects the prostate gland. It is usually a large size tumor and is located between the rectum and the urinary bladder. The benign nature of the tumor is suggested by the clear delimitation from vicinity organs. The patient usually presents with obstructive voiding symptoms, like: urinary intermittency, poor stream, a sensation of incomplete emptying and straining. Defecation symptoms might be present due to the compression of the prostatic tumor on the lower gastrointestinal tract. Imaging provides valuable information about localization and relation of the tumor with adjacent organs, it might also offer information about the nature of the tumor. Therefore, imaging information proves to be very helpful in planning surgical management which usually is complete excision. We report the case of a prostatic cystadenoma in a male patient who presented himself to the emergency unit with symptoms of acute urinary retention.
