Clinical Significance of Intra-alveolar Fibrin Deposition in Transbronchial Lung Biopsy in Patients with Organizing Pneumonia

This study examined the clinical significance of intra-alveolar fibrin deposition (IAFD) in transbronchial lung biopsy specimens obtained from patients with organizing pneumonia. Pathological reports of transbronchial lung biopsies performed between 2004 and 2012 were reviewed to identify cases of intra-alveolar organization with or without fibrin deposition. Clinical charts, computed tomography images, and transbronchial lung biopsy specimens...
