[Small bowel obstruction caused by immunosuppressive therapy after a liver transplant].

This case report describes an extremely rare cause of small bowel obstruction. A female patient who was liver transplanted seven years earlier and had been in immunosuppressive therapy since then presented with clinical and radiological manifest small bowel obstruction and surgery followed. The surgical finding was a segment near the terminal ileum with three separate stenoses in which the most oral was causing the obstruction. Histology evaluation of the stenoses revealed infiltration of lymphoid tissue and the stenoses tested positive on Epstein-Barr virus. The patient was later confirmed to be suffering from post-transplant lymphoproliferative disease.
