Hydatidosis is a relatively frequent parasitic disease in some geographical areas and is caused by infection with Echinococcus granulosus larvae leading to the development of cysts. The most frequently affected organs are the liver and lungs. Splenic involvement alone is rare and produces mild abdominal discomfort and a palpable mass in the left hypochondriac region. The treatment of choice is surgery. Radical surgery (splenectomy) is recommended, especially in large cysts. Conservative procedures are employed in pediatric patients or unresectable cysts. Laparoscopic techniques have had limited success.
