Solid cerebral echinococcosis mimicking a primary brain tumor.
Solitary brain affection is rare in echinococcosis. We report the case of a 35-year-old woman presenting with symptomatic grand-mal epilepsy due to a right frontal, partially cystic space-occupying lesion. Pre-operative computed tomography and magnetic resonance imaging (MRI) suggested a cystic astrocytoma. However, histological examination yielded the diagnosis of a 'chitinoma', a rare subtype of solid cerebral hydatid disease (echinococcosis). It mimicked a primary brain tumor and, therefore, posed a diagnostic problem. We present the--to our knowledge--first MRI scans in a case of a histologically proven chitinoma.
