Calcified cerebral hydatid cyst.

A 32-year-old patient with a lifelong history of epileptic attacks is described. A skull X-ray showed a round calcified nonhomogenous left frontotemporal mass. A CT scan confirmed its presence, as well as displacement of the left lateral and the third ventricles. At surgery a calcified inactive hydatid cyst was totally removed. Full recovery took place two months later. A differential diagnosis of hydatic cysts should be made when a calcified brain mass is found in patients from an endemic echinococcosis area.
