Intrahepatic Portal Vein Aneurysm: A Case Report of an Uncanny Late Complication of Liver Transplantation.

Background: Whereas chronic rejection, opportunistic infections, post-transplant lymphoproliferative disorder, hemophagocytic lymphohistiocytosis, biliary tract issues, and cardiovascular side effects of immunosuppressive drugs are frequently reported as late complications in liver transplanted patients, intrahepatic portal venous aneurysm following liver transplantation remains exceptional and unusual.

Case Report: We report the case of a 25-year-old man who underwent a liver transplantation in 1997 because he had glycogen storage disease type 4. The patient developed a late postoperative complication, an intrahepatic portal aneurysm, and 2 episodes of acute cholangitis.
