Stroke in a patient of anaphylaxis-a case report and brief review

Int J Emerg Med. 2023 Oct 17;16(1):74. doi: 10.1186/s12245-023-00548-3.

Abstract

Background: The use of nonionic low-osmolar contrast media has significantly reduced the risk of hypersensitivity reactions. Despite this, severe reactions continue to occur unpredictably. An ischemic stroke in the setting of anaphylaxis is extremely rare.

Case report: A 64-year-old male with no prior allergies went into anaphylactic shock following the administration of iohexol which improved after treatment. He later developed a multi-territorial ischemic stroke.

Conclusion: An ischemic stroke in the setting of an anaphylaxis is a rare occurrence, which can be attributed to multiple factors in our patient.
