🫁 In the first part of the Nodular Pattern module, we discussed two major nodular distributions in diffuse lung disease:
✔ Perilymphatic nodules
✔ Random nodules
The discussion included:
• Sarcoidosis and its mimics
• Drug-induced sarcoid-like reaction
• Simple silicosis and other pneumoconioses
• End-stage sarcoidosis
• Complicated silicosis
• Practical distinction between perilymphatic and miliary patterns
However, in daily practice, the most challenging nodules are often the centrilobular nodules.
The upcoming session will focus on a practical diagnostic approach to:
🔹 Centrilobular ground-glass nodules
🔹 Centrilobular soft-tissue nodules
🔹 Tree-in-bud pattern
Rather than memorizing differential diagnosis lists, the emphasis will be on pattern analysis, practical reasoning, and identifying the key imaging clues that narrow the diagnosis.
The attached 7-minute video is taken from the conclusion of the previous session and provides an introduction to the topics that will be covered next.
For colleagues who missed earlier sessions, recordings remain available for newly registered participants.
