Pulmonary alveolar proteinoisis (PAP) is a rare disease characterized by accumulation of proteinaceous material in the alveolar spaces. Here, we report a case of mild dyspnea with incidental 'crazy-paving' pattern on chest computed tomography (CT). Further evaluation and bronchoscopy found to have PAP.
