Vascular complications after liver transplantation are readily detected with ultrasound (US) and are well described. Less attention has been paid to non-vascular complications of liver transplantation, which are equally readily detected on US without the need to recourse to further imaging. The types, frequency and features of non-vascular complications are described in this review, with emphasis on biliary complications, types of fluid collections and the features of post-transplant lymphoproliferative disorder.
