Intraprostatic Hydatid Cyst: An Unusual Presentation

Abstract

A case of intraprostatic cyst is reported. The patient presented with a completely evacuated hydatid cyst of the prostate. The intraprostatic cystic cavity that was communicating with the urethra developed urinary stones. The patient had transurethral resection of the prostate, the stones in the cyst were pushed into the bladder and fragmented using a ballistic lithotripter. Pathological examination concluded to a prostatic hydatid cyst that had evacuated through the urethra and was complicated by stone formation within the residual cavity. Postoperative course was uneventful and follow-up did not show evidence of recurrence. This is the first case of hydatid cyst of the prostate to present as an intraprostatic stone pouch.

Genitourinary Hydatid Disease: A Review

“…Heart, spleen, kidney, and brain constitute only 10% of cases [8][9][10][11][12]. Genitourinary tract infestation is rare and kidneys are the most commonly affected, constituting for 1-5% of all cases [10,12,13].…”

“…Heart, spleen, kidney, and brain constitute only 10% of cases [8][9][10][11][12]. Genitourinary tract infestation is rare and kidneys are the most commonly affected, constituting for 1-5% of all cases [10,12,13]. Genitourinary hydatid (GUH) patients are usually asymptomatic on rupture of the cyst and are diagnosed many years later until being evaluated for other symptoms [7,14].…”

“…Adrenal gland is involved in less than 1% cases. [15,16] Pelvic echinococcosis (PE) is rare, with an incidence of 0.2-2.25% and retrovesical location is even rarer [10,11,[17][18][19]. Bladder, prostate and even testis have been reported as sites for HD.…”

“…Bladder, prostate and even testis have been reported as sites for HD. [7] Hydatid cysts (HC) in the peritoneal cavity or pelvis are usually a result of spontaneous rupture from a primary liver focus or following surgical inoculation [10,20]. Pelvic and retrovesical locations are considered primary if no other site is affected [6,10,12,21].…”

“…[7] Hydatid cysts (HC) in the peritoneal cavity or pelvis are usually a result of spontaneous rupture from a primary liver focus or following surgical inoculation [10,20]. Pelvic and retrovesical locations are considered primary if no other site is affected [6,10,12,21]. Mostly pelvic HC coexist with hepatic HC, detected before or on simultaneously, hence most of these cysts are secondary [10,12,22].…”
