RESUMEN
INTRODUCTION: Although wasp stings can cause local reactions such as pain, flare, edema, swelling and severe reactions, including anaphylaxis; neurological vascular complications are rare. CASE REPORT: We report a case of a 36-year-old male who developed focal neurological symptoms after a wasp sting. The brain MRI showed an infarct in the left dorsal medulla. The blood test has showed an elevated level of venom-specific IgE antibodies and the skin test with wasp venom was highly positive. Improvement occurred rapidly after treatment with methylprednisone. The postulated mechanisms include vasoconstriction and platelet aggregation secondary to an injection of distinct allergens contained in wasp venom. CONCLUSION: It would thus be important to ask patients about any recent wasp sting, in order to provide appropriate treatment.
