Crazy paving (medicine)
Medical sign on CT of the chest / From Wikipedia, the free encyclopedia
Crazy paving refers to a pattern seen on computed tomography of the chest, involving lobular septal thickening with variable alveolar filling. The finding is seen in pulmonary alveolar proteinosis,[1] and other diseases.[2] Its name comes from its resemblance to irregular paving stones, called crazy pavings.[3]
