Brainstem glioblastoma multiforme in a patient with NF1

Abstract

This case report presents the first known case of a brainstem glioblastoma multiforme (GBM) in a patient with neurofibromatosis type 1 (NF1). While research has proposed that larger germ-line mutations in NF1 may be the driving factor that predisposes patients with NF1 to high-grade astrocytomas, this patient had a nonsense mutation in the NF1 gene, suggesting a variant tumorigenesis. Limited data on targeted immunotherapy for NF1 patients with a GBM have been reported and more data are required before targetedtherapies could be proven as second-line treatment options.
