Exophytic pontine glioblastoma multiforme (GBM) is a highly malignant tumor of posterior
fossa, which is quite rare and such tumor presenting as cerebellopontine (CP) angle
mass is even rarer. Here, we describe a 12-year-old boy who presented with imbalance
on walking and facial nerve paresis. Magnetic resonance imaging of the brain revealed
an irregular ring enhancing mass lesion of the CP angle, which was initially thought
to be a tuberculoma, but was later confirmed to be a GBM. Clinical and radiological
differentiation of uncommon lesions of CP angle in children is discussed with brief
review of pertaining literature.
