Cerebral hydatid disease.

Although hydatid disease of the liver and lungs is common in South Asia, involvement of the brain is relatively rare. Two cases of cerebral echinococcosis are presented. One case involved the brain, kidney, heart and spleen. The case is unusual because of the multiplicity of intracranial lesions and sparing of the liver and lungs. The other case is a classical cerebral hydatid cyst. Both cases were confirmed histologically.
