Info
Diffuse bilateral "crazy paving" pattern is present with increased septal lines and ground-glass opacity involving secondary pulmonary lobules. Although the upper and lower lobes are both involved, the upper lobes are involved more severely.
Case Discussion
The "crazy paving" pattern (increased septal lines + ground-glass opacity) was initially described as pathognomonic for pulmonary alveolar proteinosis, but other causes including haemorrhage and infection have also been described.
