Background: Hydatid pathology is endemic in our region. Although hepatic and pulmonary sites are the most common, the parasite can implant in any part of the body. We will report an exceptional case of retro-vesical hydatid cyst complicated by bowel obstruction. Case presentation: 45-year-old patient, admitted to the emergency department for an occlusive syndrome, the clinical examination found, distended tympanic but flexible abdomen, rectal examination: empty bulb. The biological assessment was without particularity. An abdominopelvic CT showed a cystic mass in the Douglas pouch with caliber disparity of bowel and intestinal distension upstream evoking a retro-vesical hydatid cyst. The patient was operated, a monobloc resection of hydatid cyst was performed. The postoperative course was simple. The biological analysis confirmed the diagnosis of retro-vesical hydatid cyst. Conclusion: The retrovesical localization of hydatid cyst is rare, often asymptomatic, the clinical signs occur at a stage where the volume of the cyst is quite important. The diagnosis is often made by ultrasound coupled with CT. The hydatid serology has a great value of diagnostic orientation. The treatment is surgical based on a total perkystectomy. In an endemic area, any pelvic cystic mass must evoke a hydatid cyst.
