Alveolar proteinosis is a rare disease characterized by filling of the alveolar spaces with PAS positive material due to an abnormality in surfactant metabolism. The diagnosis is based on the suggestive HRCT pattern (crazy paving) and the characteristic features of BAL fluid (Broncho Alveolar Lavage) - Usually between 30 and 50 years old. - Nonproductive cough, fever, and mild dyspnea. - Prognosis has improved since the advent of treatment using bronchoalveolar lavage. #Clinical #Radiology #CTChest #AlveolarProteinosis #CrazyPaving #RadiologyAssistant
