概括
对比诱导性脑病变 (CIE) 是一种罕见的神经并发症,用于含的对比剂 (IC). 这个案例突出了一个自发康复的患者,过敏测试呈阴性,强调了对这种不良影响的认识.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 过敏和免疫学 过敏和免疫学
背景情况:
- 血管内含的对比剂 (IC) 很少会导致神经系统并发症,如对比诱导脑病变 (CIE).
- 通常在血管造影手术和动脉瘤治疗后报告CIE.
- 一名61岁的妇女在胸部血管CT后出现了暗示感染的症状.
研究的目的:
- 报告一种疑似对比诱导脑病变 (CIE) 的病例,该病例发生在含有的对比剂后.
- 调查离子对比剂与神经症状之间的潜在联系.
- 评估患者对对比剂过敏测试的反应.
主要方法:
- 使用Iomeprol进行胸部AngioCT.
- 患者在手术后出现了急性混乱,行为变化和皮疹.
- 过敏学评估包括用各种含的对比剂进行贴片和皮肤刺伤测试.
主要成果:
- 病人经历了急性神经症状和皮疹 IC 管理后几个小时.
- 部CT和腰部穿刺是不起眼的.
- 对多重含的对比剂的过敏测试在48小时和96小时后呈阴性.
- 患者在48小时内自发改善.
结论:
- 对比诱发性脑病变 (CIE) 是一种罕见的,急性和短暂的,用于含的对比剂的并发症.
- 尽管过敏测试呈阴性,但建议避免IC.
- 对于临床医生来说,提高对CIE的认识至关重要,可能会导致过敏学家咨询.

7.1K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

1.3K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...
