We report the case of a 56-year-old patient who underwent left single lung transplantation for idiopathic pulmonary fibrosis (IPF). Despite the high level of immunosuppression after the surgery, there was rapid progression to IPF in the native (right) lung as demonstrated by thoracoscopic lung biopsy. After 104 days on mechanical ventilation (MV), the patient underwent right lung transplant and was discharged from the hospital on postoperative day 26.
