[Splenic echinococcosis--a rare differential diagnosis in a cystic lesion of the spleen].

Cystic tumours of the spleen are generally rare and a parasitic origin is relatively improbable. Our case report, however, shows that in case of a splenic cyst, differential diagnosis must always consider the possibility of echinococcosis. We report on a patient suffering from a cystic lesion of the spleen where radiology yielded the final pointer to diagnosing an echinococcosis of the spleen.
