Necrotizing sarcoid-like granulomatosis is one of five forms of pulmonary disease characterized histologically by angiitis and granulomata formation. Although there have been several reports of the clinical and pathological characteristics of the disease, there has been little reported radiographic correlation. ⋯ The radiographic finding of diffuse lesions, either bilateral nodules or nodular densities with or without cavitation, should prompt definitive diagnostic evaluation. Tissue diagnosis is imperative as necrotizing sarcoid-like granulomatosis has a relatively good prognosis when compared with other similar granulomatous diseases.
