Mesenteric plexiform neurofibroma: computed tomography appearance.

Gastrointestinal involvement in von Recklinghausen's disease is usually in the form of neurofibromas and leiomyomas. Very rarely, plexiform neurofibromas may be seen involving the bowel wall and myenteric plexus with secondary minor involvement of the mesentery. This report describes the computed tomography morphology of a plexiform neurofibroma extensively involving the mesentery with minor involvement of the bowel wall.
