Differential diagnosis on HRCT
Most of our knowledge about imaging findings in interstitial lung disease comes from
Differential diagnosis ... four patterns: ... reticular, nodular ... histiocytosis or honeycombing ... #Diagnosis #Radiology
The fourth pattern includes abnormalities that result in decreased lung attenuation or air-filled lesions.
These include:
- Emphysema

Perilymphatic distribution
Perilymphatic nodules are most commonly seen in sarcoidosis.
They also occur in silicosis, coal-worker's pneumoconiosis and
