This case involves an otherwise healthy middle-aged woman who suddenly died after undergoing a medical workup at her local hospital and being discharged. She presented to the emergency room 3 weeks before her death with complaints of chest pain. She was seen by an emergency room physician who requested an EKG and a CXR. Both tests showed no abnormalities, and the patient was discharged with no diagnosis. She presented to her primary care physician several days later complaining of fever and was diagnosed with the common cold. The patient was prescribed a steroid nasal spray. 2 weeks later, the patient collapsed while at work. She was immediately rushed to the emergency room but died en route. The autopsy revealed a mediastinal abscess, a bacterial infection in the lung, and fat build-up on the artery walls.
