A Case of Sarcoidosis and Galaxy Sign: Diagnostic Dilemma

Abstract

The galaxy sign was first reported in pulmonary sarcoidosis. From those reports sign became known as one of the characteristic computed tomography (CT) findings of sarcoidosis. Notable feature of Galaxy sign is dense central portions surrounded by partially discrete small nodules. These nodules contain caseating or non‐caseating granulomas. Galaxy sign is considered useful signs indicative of pulmonary sarcoidosis. However, pulmonary tuberculosis may also show this finding.

We report a patient who mimic pulmonary tuberculosis in our case. Clinicians should be aware to differentiate and evaluate further before starting treatment for pulmonary tuberculosis in these patients.
