Pulmonary alveolar proteinosis in a child: HRCT findings before and after bronchoalveolar lavage.

Abstract

We demonstrate the high-resolution computed tomography (HRCT) findings of pulmonary alveolar proteinosis in a child before and after bronchoalveolar lavage. The CT pattern in our case differs from the pattern described in previous reports. We found a more homogeneous distribution of the pulmonary changes and a "crazy paving" pattern. High-resolution CT may be helpful in the differential diagnosis of this rare disease and in the follow-up of the pulmonary changes after bronchoalveolar lavage.
