[MR and CT patterns of neurocysticercosis]

MRI and CT manifestations were studied in five cases of neurocysticercosis. As demonstrated by long-term follow-ups the disease usually causes multiple lesions the morphology of which depends on the life cycle of the parasite. Tissue lesions consist of three main types: 1) vital cysticerci, 2) inflammatory parenchymatous reactions following degenerating cysts and 3) calcified granulomas. MRI provides all information that is given by CT except for small calcifications which are usually missed. Morphological details of vital cysticerci like cyst wall and scolex are better outlined by MRI. When i.v. contrast medium is applied, it leads to nodular or annular enhancement of inflamed tissue. The sensitivity of MRI towards edema caused by parasite exceeds that of CT by several weeks. CT and MRI are complementary methods providing at the present time the highest degree of specificity in diagnosing neurocysticercosis.     «
