Pathophysiology

These tumors have a predilection to originate from the left side. Most are located in the pons; however, medulla and midbrain may be involved as well. Brainstem gliomas are highly aggressive brain tumors.

Anatomic location determines the pathophysiological manifestation of the tumor. With tectal lesions, hydrocephalus may occur as a result of fourth ventricular compression. With pontine and cervicomedullary lesions, cranial nerve or long tract signs are observed commonly.
