From: Imaging indications and findings in evaluation of lung transplant graft dysfunction and rejection
Primary graft dysfunction: imaging and transbronchial biopsy findings. The patient was 2 days status-post left lung transplant and developed increasing hypoxemia. Axial CT images (a) shows smooth interlobular septal thickening with ground-glass opacities in the transplanted left lung. These findings are typical of primary graft dysfunction but are indistinguishable from acute rejection. Transbronchial biopsy (b) from a different lung transplant patient with primary graft dysfunction showing diffuse alveolar damage. Note hyaline membranes (arrows)
