Abstrakt: Pulmonary aspergillosis causes a wide spectrum of disease, ranging from asymptomatic airway colonization to severe invasive disease, contingent on the host's immune status and underlying pulmonary anatomy. The invasive form of aspergillosis is a rare occurrence in the immunocompetent population. Nevertheless, patients with a compromised innate immune response are at greatest risk. 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.
