Chronic Pulmonary Aspergillosis with Pleuroparenchymal Fibroelastosis-like Features

A 64-year-old man who presented with repeated bouts of pneumothorax was admitted to our hospital because of gradually progressive dyspnea and repeated episodes of a fever. The physiological, radiological and pathological findings were consistent with pleuroparenchymal fibroelastosis (PPFE). In addition, the serumspecific precipitating antibody for Aspergillus was positive. After the administration of voriconazole, a marked improvement was observed in the imaging and physiological findings. Given this clinical course, we diagnosed the patient with PPFE secondary to aspergillosis. The present case suggests that a therapeutic approach based on the cause of secondary PPFE may improve the prognosis of PPFE.
