Pulmonary Alveolar Microlithiasis in a Patient Requiring Allotransplant

A woman in her late-50s with a 3-year history of progressive hypoxemic respiratory failure, severe pulmonary hypertension, and right ventricular dysfunction was referred for lung transplant assessment. She noted persistent cough and dyspnea on exertion. Pulmonary function testing demonstrated a severe restrictive defect. High-resolution computed tomography of the thorax showed bilateral diffuse interlobular and intralobular septal thickening and ground-glass opacities with extensive calcific deposits (Figure  1).
