Pulmonary Sarcoidosis: A Pictorial Review.

Area of Science:

• Pulmonology
• Radiology
• Pathology

Background:

• Sarcoidosis is a multisystem granulomatous disease predominantly affecting the lungs.
• No definitive diagnostic test for sarcoidosis exists, making imaging crucial.
• Radiographic findings are key to diagnosing sarcoidosis.

Purpose of the Study:

• To illustrate the diverse thoracic imaging manifestations of sarcoidosis.
• To aid clinicians in diagnosing this complex condition.
• To highlight both classic and atypical presentations.

Main Methods:

• Review of radiographic findings in patients with sarcoidosis.
• Correlation of imaging findings with pathological evidence.
• Illustration of characteristic and unusual imaging patterns.

Main Results:

• Classic findings include lymphatic pathway granulomas, lymphadenopathy, and fibrosis.
• Atypical manifestations involve bronchi, pulmonary arteries, and the heart.
• Fungal colonization can also be an associated finding.

Conclusions:

• Thoracic imaging plays a vital role in diagnosing sarcoidosis.
• Familiarity with a wide spectrum of imaging findings is essential.
• Accurate interpretation of imaging aids in the management of sarcoidosis.
