Intraperitoneal, pelvic and retroperitoneal multiple hydatid cysts

Hydatid disease is relatively frequent in our country. Asymptomatic hydatid disease may present with complications, but unusual locations as well as multiple primary or secondary hydatid disease pose special diagnostic and therapeutic challenges. In humans, hydatid disease commonly involves the liver (75%) and the lungs (15%). The remaining (10-15%) of the cases involve other regions of the body. Synchronous multiple cysts represent less than 2% of all cases. The disseminated intra-peritoneal hydatid disease is a very rare finding. We report such a presentation wherein the abdominal cavity, retro peritoneum and pelvis contain multiple hydatid cysts. The challenges encountered in the diagnosis and treatment of this patient are highlighted.
