CT 检查常用造影剂进行增强,但造影剂有时可引起严重的合并症,痉挛发作就是其一。多数学者认为这与颅内病变有明显关联。其中以转移性脑瘤与神经胶质瘤占绝大多数;还可见于播散性坏死性脑白质病、精神运动性癫痫发作及血管内皮瘤等。作者指出,造影剂诱发痉挛发作,除一例为诱发原有精神运动性癫痫发作外,余均为局部或全身性痉挛发作。各种造影剂注入过程中或注完后均可引起发作。除原有疾病引起癫痫发作外,应用造影剂引起痉挛发作亦不少,这种现象在同一患者有反复发作的倾 CT contrast commonly used contrast agent to enhance, but contrast agents can sometimes cause serious complications, spasm is one. Most scholars think this is obviously associated with intracranial lesions. Among them, metastatic brain tumors and gliomas accounted for the vast majority; also found in disseminated necrotic leukoencephalopathy, psychomotor seizures and vascular endothelial tumors. The authors point out that the contrast agent induced spasm attack, in addition to a case of induced psychomotor seizures, the rest are local or systemic spasms.

In addition to the original disease caused by seizures, the application of contrast agent caused by seizures are also many, this phenomenon in the same patients have recurrent episodes of dumping
