We report a case of a nodular nongranulomatous vasculitis of the lung detected by 18F-FDG PET/CT. A 51-year-old woman with fever of unknown origin underwent 18F-FDG PET/CT, which showed multiple and bilateral pulmonary nodules at CT scan with increased radiopharmaceutical uptake in the largest one (20 mm in diameter). On the basis of the PET/CT findings, the patient was referred for excisional biopsy of the largest pulmonary nodules suspicious for neoplastic disease. Histological examination demonstrated the presence of an obliterative vasculitis with interstitial pulmonary perivascular inflammation.

Abstract
We report a case of a nodular nongranulomatous vasculitis of the lung detected by 18F-FDG PET/CT. A 51-year-old woman with fever of unknown origin underwent 18F-FDG PET/CT, which showed multiple and bilateral pulmonary nodules at CT scan with increased radiopharmaceutical uptake in the largest one (20 mm in diameter). On the basis of the PET/CT findings, the patient was referred for excisional biopsy of the largest pulmonary nodules suspicious for neoplastic disease. Histological examination demonstrated the presence of an obliterative vasculitis with interstitial pulmonary perivascular inflammation.
