Deep neck space infection and viral myocarditis related to coronavirus disease 2019 (COVID-19) have both been described in the medical literature. However, there are only three reported cases of retropharyngeal infection as a presenting pathology in the setting of COVID-19. A 26-year-old woman presented to the emergency room with fever and neck swelling and pain 1 month after COVID-19 infection. A computed tomography scan of the neck demonstrated tonsillitis with retropharyngeal infection. She was also found to have heart failure with an ejection fraction (EF) of <20% due to acute myocarditis. Her infection resolved and the EF improved to 40% prior to discharge. Our case is the first to describe retropharyngeal infection as a late complication in an adult with a history of COVID-19 several weeks previously. It also presented a clinical challenge in terms of tailoring goal-directed medical therapy to manage severe left ventricular dysfunction caused by myocarditis.
Learning points: Deep neck space infections may be a long-term complication of SARS-CoV-2 infection.Fever, neck swelling and pain should arouse suspicion of deep neck space infection even in adults.Acute viral myocarditis in the setting of SARS-CoV-2 can present many weeks after the initial infection.
