‘crazy-paving’ pattern on CT

278.All are true regarding airspace diseases except
a. Wegener's granulomatosis  may show  cavitation  on CT scan
b. In cryptogenic organizing pneumonia, areas of consolidation  most pronounced in the periphery and lower zones of the lungs
c. in chronic eosinophilic pneumonia, the changes tend to be in the upper zones and  parallel to the chest wall
d. transient and migratory opacities , unaccompanied by significant constitutional disturbance favour  diagnosis of an eosinophilic pneumonia.

e. ‘crazy-paving’ pattern on CT is noted in alveolar proteinosis.



278.----b---In cryptogenic organizing pneumonia, areas of consolidation  are most pronounced in the periphery and upper zones of the lungs.(CHAPTER 21 – Airspace Diseases,Adam: Grainger & Allison's Diagnostic Radiology, 5th ed)
