CTICasesSarcoidosis
Imaging findings
Progressive massive fibrosis, "galaxy sign" (clusters of tiny nodules), and mediastinal/hilar lymphadenopathy without calcification.
Key takeaways
The "galaxy sign" is highly suggestive of sarcoidosis. While silicosis is a consideration in patients with occupational exposures (e.g., ceramics/clay), the lack of discrete, dense fibrotic nodules and the presence of "shaggy" conglomerate masses favor sarcoidosis.
