A 20-year-old man was seen in the office for an abnormal chest CT scan. He had been in good health until a month prior, when he developed an upper respiratory tract infection with a congested cough, fever, and shortness of breath. He later developed pleuritic chest pain in the left upper hemithorax. Symptoms resolved except for the pain, which radiated to the left lateral hemithorax. The pain was severe, constant, and unbearable, so he went to the ED. Pain was controlled adequately by pain medications. He was told to follow up with a pulmonologist because of abnormal chest imaging.
