Mesenteric involvement in neurofibromatosis type 1: CT and MRI findings in two cases

We report computerized tomographic and magnetic resonance imaging findings of neurofibromatosis type 1 with mesenteric involvement in two patients. The first patient was a 13-year-old female with a panmesenteric plexiform neurofibroma with segmental involvement of the bowel wall; she had a 3-year history of abdominal pain. The second patient was a 60-year-old female who presented with malignant transformation of multiple mesenteric neurofibromas 4 months after primary operation.
