title: Pulmonary artery involvement in Takayasu's arteritis with lung infarction and pulmonary aspergillosis.
abstract: We describe a patient with a chronic case of pulmonary involvement of Takayasu's arteritis in the resected lung. A 49-year-old woman was first diagnosed with Takayasu's arteritis at age 30 years. On her first admission, she presented with Takayasu's arteritis and pneumonia with cavitation in the left lung. After recovering from pneumonia, she was treated initially with prednisolone, 30 mg/day, and remained well until she developed hemoptysis at age 34 years. Findings suggesting aspergilloma were found in the same lobe on chest x-ray film when she was 46 years of age. By age 49 years, the hemoptysis became massive, and she was admitted for surgery. Left upper lobectomy and partial resection of S6 and S8 pulmonary segments were performed. Histologic analysis of the resected lung revealed typical pathologic findings of pulmonary artery involvement in Takayasu's arteritis, such as stenosis recanalization and a vessel-in-vessel feature, but not active vasculitis. Infection probably occurred in the cavity of the infarcted tissue. Pulmonary artery involvement is common in Takayasu's arteritis, but the aspergilloma in this corticosteroid-treated patient is an uncommon complication.
