Case ReportsF-18 FDG PET/CT findings in pulmonary necrotizing sarcoid granulomatosis.
Necrotizing sarcoid granulomatosis (NSG) is a rare systemic disease that was described by Liebow in 1973. Dyspnea and chest pain may be present, as in our first patient; however, 25% of patients are asymptomatic, as our second patient. ⋯ We report 2 cases, confirming that the lesions of NSG are FDG positive, showing a typical pattern of multiple bilateral lung nodules (imaged with PET/CT in 1 case). FDG imaging has a potential role when this distribution is observed on CT, to guide the surgical biopsy and show the actual extent of the disease.
