Imaging findings showing evolution of bronchiolitis obliterans to restrictive allograft syndrome. The patient initially presented with decreased FEV1 and mid-flows. Initial axial CT images (a and b) show mosaic attenuation, likely due to air-trapping. Transbronchial biopsy was negative for infection and acute rejection and the diagnosis of bronchiolitis obliterans syndrome was made. Follow-up CT images (c and d) after 3 years show evolution of changes with upper lobe predominant subpleural pleuroparenchymal fibrotic changes typical of restrictive allograft syndrome
