KEY CLINICAL MESSAGE:
‘Crazy paving’ is referring to the superimposition of ground-glass opacity and linear pattern resembling irregularly shaped paving stones on CT images. Initially ‘crazy-paving’ was described as pathognomonic sign for alveolar proteinosis. Subsequently, this pattern has been reported in a variety of idiopathic, neoplastic, infectious, inhalational, and sanguineous disorders of the lung. We demonstrated atypical computed tomography images of lung adenocarcinoma demonstrating both solid and crazy paving appearance.
