[Echinococcus cysticus--rare differential diagnosis of a splenic cyst].

Splenic involvement in hydatid disease is uncommon, representing less than 2% of all human organ manifestations by echinococcus cysticus. We report on the rare case of an isolate splenic infection. The case history and the clinical findings were compatible with a traumatic cyst. Ultrasound, CT and MR findings are discussed.
