Necrotizing sarcoid granulomatosis: computed tomography and pathologic findings

J Comput Assist Tomogr. 1995 Nov-Dec;19(6):920-3.


Objective: To describe the CT findings and corresponding pathological findings of necrotizing sarcoid granulomatosis (NSG).

Materials and methods: We reviewed the high-resolution CT and macroscopic and histologic findings in three pathologically proven cases of NSG.

Results: The CT findings consisted of one case each with single nodule, multiple nodules, and parenchymal opacification. The abnormalities were peribronchovascular or subpleural in distribution. Histologically, all patients had sarcoid-like granulomas with central necrosis and granulomatous vasculitis. The CT findings correlated closely with the gross pathologic findings.

Conclusion: We conclude that the CT manifestations of NSG reflect the variable macroscopic pathologic findings.
