More than half of allogeneic haematopoietic stem cell transplant (HSCT) recipients develop graft-versus-host disease (GVHD), which remains a major cause of morbidity and mortality. HRCT findings in patients with GVHD are non-specific: diffuse interstitial and alveolar infiltrates are the most prominent features [27] . Depending the interstitial and alveolar component, a crazy-paving pattern can also be seen. On biopsy multiple hyaline membranes and fibroproliferative alterations can be seen, caused by the interstitial fibrosis and responsible for the linear pattern on CT. The multiple exudates into the alveolae are responsible for the ground-glass attenuation [28] .
