Malignant peripheral nerve sheath tumors (MPNST) in neurofibromatosis type 1 (NF1): diagnostic findings on magnetic resonance images and mutation analysis of the NF1 gene.

Abstract

This study provides evidence for certain radiographic findings on MRI in PNF of NF1 patients that have to be considered as signs of malignancy, in particular indicating an MPNST. These findings are especially valuable in the long term follow-up control of patients with large tumors (plexiform neurofibromas).
