title: [A man with a 'galaxy sign'].
abstract: This brief report describes the radiographic images of a 29-year-old man with asymptomatic sarcoidosis. On a CT-scan a coalescent granuloma with a central core and peripheral nodules mimics a globular cluster galaxy; therefore it is called 'galaxy sign'. This is a classic finding in a granulomatous disease like sarcoidosis.
