Entrance of metrizamide into an intraventricular cysticercosis cyst.

Although many computed tomographic (CT) features of cysticercosis cerebri have been described [1 -5], the recognition of ventricular cysticercosis cysts on plain CT scans is stili generally difficult or impossible . Recently, we observed entrance of metrizamide into a ventricular cysticercosis cyst after ventriculography. This new feature may be specific for intraventricular cyst icercosis cysts , particularly in conjunction with other previously recognized features of these cysts on contrast studies [5].
