Abstract

We present a case of pulmonary alveolar proteinosis in a 27 year old male, in which high resolution computerised tomography shows a typical crazy paving pattern. This test led to a specific differential diagnosis, in spite of the lack of specificity in the clinical presentation. The bronchoalveolar wash was not conclusive and the definitive diagnosis was made with a transbronchial biopsy. We review the most characteristic aspects of this rare disease and of the crazy paving pattern in high resolution CT.
