Cough and Progressive Pleuritic Chest Pain With an Enlarging Cavity on Imaging.

A 49-year-old woman sought treatment at the hospital for evaluation of an enlarging cavitary mass of the right lung associated with worsening ipsilateral pleuritic chest pain and cough. She had recent hospitalizations for complications relating to recurrent lung abscesses, including one in which she underwent wedge resection of the right lung. She had been treated with several courses of antibiotics, which only temporarily relieved her symptoms. She did not report any fevers, chills, skin changes, diarrhea, or changes to her bowel habits. Her long-term medications included albuterol, dapsone, and prednisone 15 mg or 20 mg doses alternating daily. Her only past medical history was asthma and primary cutaneous pyoderma gangrenosum. The patient never smoked and did not report any recent sick contacts.
