Hepatic and Retrovesical Hydatid Disease: A Rare Case of Multivisceral Hydatidosis

Abstract

Hydatidosis is endemic in Morocco. Although hepatic involvement is common, pelvic and retrovesical localizations are exceptionally rare. This study reports the observation of a patient aged 60 years who has presented for one year with paroxysmal pain in the right hypochondrium and a sensation of heaviness, as well as a notion of pollakiuria. Clinical examination revealed a firm, painless, and well-defined abdominal mass extending from the right hypochondrium to the epigastric region. Abdominal and pelvic CT revealed multiple hydatid cysts in the left liver and a retrovesical cystic mass. The diagnosis of hydatid cyst of the bladder was made intraoperatively. The surgical procedure involved resecting the protruding dome, aspirating the hydatid fluid, removing the daughter vesicles, and thoroughly washing the endocyst. Early recognition and appropriate surgical and medical management are essential to prevent complications and recurrence. Strengthening primary prevention measures, particularly canine control and food hygiene, remains fundamental to reducing the burden of hydatid disease in endemic countries.
