Transaqueductal Migration of the Neurocysticercus Cyst: Two Case Report

ABSTRACT

The authors report two cases of radiologically documented transaqueductal migration of intraventricular neurocysticercus cysts. The patients had suffered from symptomatic hydrocephalus caused by neurocysticercosis. The migration of the cysts from third to forth ventricle and cisterna magna were clearly demonstrated on serial radiological studies. Since the exact route of the subarachnoid type of the neurocysticercosis has not been defined, these cases may provide a valuable clue in verifying the pathogenic pathway. The possibility of the cyst migration before surgery also should be kept in mind. The radiological appearance and the clinical significance of this condition are discussed with brief review of literatures.
