A Case of Sudden Infant Death Due to Incomplete Kawasaki Disease.

Baby’s Disease was Reaction to BCG Vaccine


Although Kawasaki disease (KD) is a self-limiting disease, it may cause sudden cardiac death. Diagnosis of KD is principally based on clinical signs; however, some infant cases do not meet the criteria. Such cases are identified as incomplete KD. The sudden death risk in incomplete KD cases is similar to conventional KD. In our 5-month-old case, he had been admitted to a hospital for a fever and suppuration at the site of Bacille de Calmette et Guerin (BCG) vaccination. However, after discharge from the hospital, his C-reactive protein (CRP) levels declined, he got indisposed and died suddenly. A medico-legal autopsy revealed myocarditis, coronaritis, platelet-aggregated emboli in coronary arteries, and myocardial degeneration, suggesting that the fatal myocardial infarction was due to thrombus emboli in the coronary arteries. Forensic pathologists therefore should pay attention to the cardiac pathology originated from incomplete KD as a potential cause in cases of sudden infant death.
