[Sarcoidosis coming from the galaxy].

Area of Science:

• Pulmonology
• Radiology
• Pathology

Background:

• Sarcoidosis is a multisystem inflammatory disease of unknown etiology.
• Clinical and radiological manifestations are highly variable and often non-specific.

Observation:

• A 23-year-old male presented with asymptomatic, multiple bilateral pulmonary nodules.
• Imaging revealed spiculated nodules with peripheral micronodules, a pattern described as the 'galaxy sign'.

Findings:

• The 'galaxy sign' is an uncommon radiological finding.
• This rare presentation was crucial in diagnosing sarcoidosis in the absence of typical symptoms.

Implications:

• The 'galaxy sign' may serve as a valuable diagnostic clue for sarcoidosis.
• Recognizing rare imaging patterns can improve diagnostic accuracy for sarcoidosis.
