Abstract
Hymenoptera stings can lead to a different range of local and systemic reactions. However, rare and unexpected reactions can develop and may be life threatening. In this paper, we present a 29-year-old female who developed anaphylactic shock followed by paraparesis and paraesthesia after a black ant sting. Her symptoms completely resolved after treatment with plasma exchange. Several studies have linked these neurological complications to delayed immunological reactions that are triggered by insect antigen.
Learning points: Environmental antigen exposure can present with immediate and delayed reactions.Weakness and paraesthesia are an unusual presentation reported after an ant sting that might be triggered due to an immunological response to an antigen, or antigen that directly causes neurotoxicity.Plasmapheresis might be an option for management of unexplained acute paraparesis and paraesthesia.
期刊介绍:
The European Journal of Case Reports in Internal Medicine is an official journal of the European Federation of Internal Medicine (EFIM), representing 35 national societies from 33 European countries. The Journal''s mission is to promote the best medical practice and innovation in the field of acute and general medicine. It also provides a forum for internal medicine doctors where they can share new approaches with the aim of improving diagnostic and clinical skills in this field. EJCRIM welcomes high-quality case reports describing unusual or complex cases that an internist may encounter in everyday practice. The cases should either demonstrate the appropriateness of a diagnostic/therapeutic approach, describe a new procedure or maneuver, or show unusual manifestations of a disease or unexpected reactions. The Journal only accepts and publishes those case reports whose learning points provide new insight and/or contribute to advancing medical knowledge both in terms of diagnostics and therapeutic approaches. Case reports of medical errors, therefore, are also welcome as long as they provide innovative measures on how to prevent them in the current practice (Instructive Errors). The Journal may also consider brief and reasoned reports on issues relevant to the practice of Internal Medicine, as well as Abstracts submitted to the scientific meetings of acknowledged medical societies.
