(a, b) Pulmonary alveolar proteinosis: 41 year old female who approximately 6 months ago presented with shortness of breath and a dry cough. A CT scan showed extensive crazy paving appearance of the lung parenchyma, ground-glass opacities with septal thickening. The patient underwent bronchoscopy with biopsy. Findings of bronchoscopy were consistent with pulmonary alveolar proteinosis.
