title: Central nervous system cysticercosis simulating an acute cerebellar hemorrhage.
abstract: We report the case of a Mexican man who suddenly developed severe occipital headache, vomiting, vertigo, and ataxia. Neurologic examination showed nystagmus and cerebellar findings. Computed tomography of the brain demonstrated a large left cerebellar cystic lesion consistent with the diagnosis of cysticercosis. The patient was treated with dexamethasone and praziquantel and required surgical removal of the lesion to prevent herniation. He recovered without neurologic sequelae. The abrupt onset of cerebellar findings is an unusual presentation of this disease. Central nervous system cysticercosis is being recognized with increasing frequency in the United States, where it is found primarily in Hispanic and Asian immigrants. The literature of central nervous system cysticercosis is reviewed and the pathogenesis, clinical presentation, and therapy are discussed.
