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.
对5例神经囊尾蚴病患者的MRI和CT表现进行了研究。长期随访表明，该病通常会引起多个病灶，其形态取决于寄生虫的生命周期。组织病变主要有三种类型：1）活囊尾蚴；2）退化囊肿后的炎性实质反应；3）钙化肉芽肿。MRI能提供CT所提供的所有信息，但通常会遗漏小钙化灶。活囊尾蚴的形态细节，如囊壁和头节，在MRI上显示得更清晰。静脉注射造影剂时，会导致炎症组织出现结节状或环状强化。MRI对寄生虫引起的水肿的敏感性比CT高出数周。CT和MRI是互补的方法，目前在诊断神经囊尾蚴病方面具有最高的特异性。
