Abstract

Low-grade brainstem gliomas (LGBSG) in children is a heterogeneous pathological entity. Tumor location, clinical course, and radiological characteristics are the main factors affecting treatment and outcome.

Most low-grade gliomas in children have an indolent course. In selected cases, the diagnosis may be solely based on magnetic resonance imaging (MRI); however, in most cases, tissue sampling is indicated.

Treatment of LGBSG is multimodal. Some lesions are followed up conservatively. The role of surgery and oncological treatments (chemotherapy and radiation) have been discussed in this chapter. Generally speaking, maximally safe resection is advised when possible. Intraoperative monitoring is mandatory during surgery, which increases patient safety.
