A rare neurological manifestation of seizure in a case of anaphylaxis following a hornet sting: case report & literature review

Anaphylaxis is a severe, life-threatening allergic reaction that can present with a variety of systemic manifestations. Neurological symptoms such as seizures or seizure-like activity are uncommon in anaphylaxis. We present the case of a healthy young male with no history of seizures who experienced anaphylaxis following a hornet sting, manifested by urticarial rashes, facial flushing, and generalized pruritus. Interestingly, he developed seizure-like activity, characterized by focal jerky movement of the left upper limb with impaired consciousness as reported by eyewitnesses. This case highlights the atypical presentation of neurological manifestations of anaphylaxis, discusses its potential pathophysiological mechanisms, and reflecting individualized management approach in relation to established guidelines.
