Summary

Imaging description

The classic appearance of pulmonary alveolar proteinosis is symmetric, predominately perihilar, ground-glass opacity with intralobular linear opacities and interlobular septal thickening (“crazy-paving” pattern) [1–3] (Figures 19.1–19.4). There is often geographic sparing of secondary lobules and periphery of the lung. Consolidation can be seen in advanced cases.

Importance

Pulmonary alveolar proteinosis is one of several conditions associated with a crazy-paving pattern on high-resolution CT. Knowledge of the different causes of this pattern can aid in preventing diagnostic errors [3].
