Diagnosis With Brief Discussion

Diagnosis
DIP (desquamative interstitial pneumonia)
Radiologic Findings
Brief Review
DIP is characterized by mild inflammation of the alveolar interstitium with relative preservation of the alveolar anatomic structure and the presence of many macrophages within the alveolar air spaces. The most common finding on the chest radiograph is the presence of ground-glass opacity in the lower lung zones. These areas of ground-glass opacity are predominantly in the periphery of lower-lung zone on HRCT scan. Irregular lines of attenuation, cystic changes, and traction bronchiectasis may also be seen but are usually not prominent.
