Granulomatous response to invasive pulmonary aspergillosis in an immunotherapy-naive host, a maladaptive response?

We present a case of a patient with known Crohn's disease who developed invasive pulmonary aspergillosis. His clinical picture was further complicated by an uncommon immune response characterized by the development of granulomas encasing the Aspergillus forms found on his lung biopsy, likely representing a maladaptive response, possibly related to the effects of his granulomatous disease in the lungs. He was successfully treated with antifungal therapy and video assisted thoracoscopic surgery with placement of thoracostomy tube drainage for a parapneumonic effusion. We will discuss the factors leading to his atypical presentation and clinical outcome.
