Pulmonary Artery Aneurysm Associated With Aspergilloma in a Patient Diagnosed With Granulomatosis With Polyangiitis

Granulomatosis with polyangiitis (GPA) is an autoimmune, necrotizing granulomatous disease that affects small- and medium-sized blood vessels. Aspergilloma is a fungal mass of Aspergillus and usually found in the preexisting cavity in lung parenchyma. Surgical resection is the mainstay of treatment of aspergilloma. In this article, we present a case of a 70-year-old male with GPA and aspergilloma who presented with massive, life-threatening hemoptysis. Further workup with a chest computed tomography (CT) pulmonary angiogram demonstrated a pulmonary artery pseudoaneurysm along the wall of the lung cavity which was emergently managed with embolization and required monitoring in the medical intensive care unit. This case report alerts clinicians to maintain a high level of suspicion for an aneurysm if the degree of hemoptysis is higher than expected.
