Abstract
Sarcoidosis and tuberculosis are two common granulomatous conditions that may share clinical and radiological presentations. The galaxy sign (sarcoid galaxy sign) is a characteristic radiological sign of pulmonary sarcoidosis on thoracic computed tomography (CT). We present the case of a patient with sarcoidosis that was initially misdiagnosed as tuberculosis, in whom the galaxy sign on CT was useful as it suggested the correct diagnosis.
