Pulmonary Alveolar Proteinosis: Crazing-Paving Appearance

A 50-year-old woman with a 2-month history of intermittent cough presented at the respiratory medicine outpatient clinic. She had a long history of obesity, hypertension, and diabetes mellitus. Her vital signs were normal. Physical examination and routine blood tests were unremarkable. However, a simple radiograph showed bilateral perihilar infiltrates and diffuse reticulonodular lesions (Figure 1A). Thoracic high-resolution computed tomography (HRCT) revealed bilateral, scattered ground-glass attenuation with interlobular septal thickening and intralobular lines (i.e., a crazy-paving appearance; Figure 1B).
