Abstract

Hereby, we report a case of a 75-year-old man who presented with a 3-day history of facial swelling and choking sensation. The only history of note was an insect bite on the left parotid gland area 3 days prior. The patient was later diagnosed with insect-bite-induced Ludwig’s angina. Enterococcus faecalis was detected on blood cultures and was presumed the source of infection. Intravenous antibiotics and corticosteroids were initiated. The patient was intubated and was subsequently made to undergo a tracheostomy insertion to establish a definitive airway. He was admitted to the intensive care unit and when his condition improved, he was transferred to the ward for full recovery. The patient spent a total of 66 days in hospital before being discharged. This case suggests that Ludwig’s angina can be caused by insect bites. However, further similar cases are needed to be documented to explore this theory.
