[Plexiform cervical neurofibroma: about a case]

Plexiform neurofibroma is a rare benign tumor of the peripheral nerves involving the conjunctiva cells of the perineurium. It is pathognomonic of neurofibromatosis type1 (NF1 or Von Recklinghausen disease). MRI is a great help in the diagnosis of this pathology. Anatomopathological confirmation is sometimes necessary, in particular in patients with no signs of NF1. We here report the case of a little girl with cervical plexiform neurofibroma revealing neurofibromatosis type 1.
