TY - JOUR T1 - Bilateral Micronodular Pulmonary Infiltrate: Is It Important to Make a Histological Diagnosis? JF - Respiratory Care SP - e69 LP - e71 DO - 10.4187/respcare.02036 VL - 58 IS - 7 AU - Kashif Ali Khan AU - JJ Gilmartin Y1 - 2013/07/01 UR - http://rc.rcjournal.com/content/58/7/e69.abstract N2 - Pulmonary alveolar microlithiasis is a rare disease characterized by the deposition of calcium phosphate within the alveoli. We report the case of a 20-year-old man with a 6-week history of cough and shortness of breath on exertion. The chest radiograph demonstrated a bilateral symmetrical micronodular pattern. High-resolution computed tomography revealed bilateral diffuse fine nodular shadowing involving the mid zones, with sparing of the apices. The patient underwent a transbronchial lung biopsy, which confirmed the diagnosis of pulmonary alveolar microlithiasis. ER -
