The parenchymal form of cerebral cysticercosis.

22 cases of the parenchymal form of cerebral cysticercosis are discussed. The parenchymal form presents a variance of appearance on computer tomography (CT). The five most common CT findings are described. They are classified as (1) completely calcified lesions, (2) cystic lesions with ring enhancement (with or without calcification), (3) nonenhancing cystic lesions; (4) homogeneously enhancing lesions, and (5) mixed parenchymal lesions.
