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 excerpt

UNLABELLED: Plexiform neurofibroma (PNF) is a typical feature of neurofibromatosis 1 (NF1). About 10% of patients with NF1 develop malignant peripheral nerve sheath tumors (MPNST), usually arising from PNF, and this is the major cause of poor prognosis. A better prognosis can be achieved if the tumors are diagnosed at an early stage. Our objective was to establish magnetic resonance imaging (MRI) criteria for...
