Brainstem glioma presenting as pruritus in children with neurofibromatosis-1.

Children with neurofibromatosis type 1 (NF1) are at increased risk of developing tumors of the nervous system. The most common intracranial tumors are low-grade astrocytomas, which most frequently involve the optic pathway, and less often, the brainstem. In cases of brainstem glioma in NF1, treatment decisions are frequently complicated by the paucity of symptoms referable to the tumor.
