Crazy paving pattern

MedGen UID:
1376678
•Concept ID:
C4476749
•
Finding
Synonyms: Crazy paving appearance; Crazy paving sign; Crazy-paving pattern; GGO and reticulation; Ground glass opacity with reticulation
 
HPO: HP:0025391

Definition

The so-called crazy paving pattern appears as thickened interlobular septa and intralobular lines superimposed on a background of ground-glass opacity, resembling irregularly shaped paving stones. The crazy-paving pattern is often sharply demarcated from more normal lung and may have a geographic outline. It was originally reported in patients with alveolar proteinosis and is also encountered in other diffuse lung diseases that affect both the interstitial and airspace compartments, such as lipoid pneumonia. [from HPO]
