Introduction: The article demonstrates, using a case report, that death fol
lowing an accident may have rarely encountered causes that are not a direct
result of trauma and that can only be detected by autopsy. Case: An uncons
cious woman aged 57 years was admitted to hospital. Despite immediate surge
ry for intracranial haemorrhage diagnosed by means of cranial computed tomo
graphy, the patient died showing clinical symptoms of circulatory depressio
n after a brief period of stabilisation. The autopsy established myocardial
infarction with hypersensitivity angiitis as the cause of death. Conclusio
n: In this case, the authors hold the opinion that the intravenous applicat
ion of antibiotics during the patient's stay in hospital resulted in hypers
ensitivity angiitis. The factors causing hypersensitivity angiitis, the mor
phological picture (clinical, histological) and therapeutic measures are de
scribed.
