Lung adenocarcinoma with mixed solid and crazy‐paving appearances

Abstract

“Crazy paving” on CT images refers to the superimposition of ground‐glass opacity and linear pattern resembling irregularly shaped paving stones. Initially, “crazy paving” was described as a pathognomonic sign of alveolar proteinosis. Subsequently, this pattern has been reported in a variety of disorders of the lung. We demonstrated CT images of lung adenocarcinoma demonstrating both solid and crazy‐paving appearances.
