Staged and combined resection of a posterior fossa ganglioglioma.

ABSTRACT:

Background

Posterior fossa gangliogliomas with extension into the cerebellopontine angle are extremely rare and can be challenging to resect because they are infiltrative and the regional neurovasculature is complex.[1,2] Tumor grade may best predict oncologic outcome.[1] Histologic grading can be used to balance surgical aggression with the risk of cranial neuropathies.

Case description

During an evaluation for headaches, a 19-year-old woman was found to have a 5.3 × 4.0 × 3.5-cm left lateral cerebellar and cerebellopontine angle tumor, with an apparent intrinsic origin and significant exophytic extension. The lesion was minimally enhancing and partially cystic and had significant calcifications. On examination, she was neurologically intact, with the exception of mildly de
