Abstract
Plexiform neurofibromas usually occur in the neck, pelvis, and extremities. Jaws and
oral cavity plexiform neurofibromas have also been described. Magnetic resonance (MR)
patterns for neurofibromas are typical. They include low-to-intermediate signal intensity
on T1-weighted images, enhancement of the solid component of the tumor after contrast
medium administration, heterogeneity on T2-weighted images, and in some cases, multiple
target signs due to a collagen central area. We report MR findings of two neurofibromatosis
type 1 (NF1) patients with enlarging tongue plexiform neurofibromas.
