CTICasesBronchiolitis Obliterans
Imaging findings
Lung transplant patient presented with shortness of breath. CT imaging showed mosaic attenuation, air trapping, and a nodular/fibrotic pattern in the upper lobes, indicative of bronchiolitis obliterans and subsequent allograft fibrosis.
Key takeaways
Bronchiolitis obliterans is a major cause of graft dysfunction in lung transplant recipients, manifesting with obstructive physiology and distinct imaging features like mosaic attenuation. It may progress to involve restrictive fibrotic patterns.
