Unveiling the Uncommon: Primary Extra-axial Pilocytic Astrocytoma of the Cerebellopontine Angle

Glial tumors in the cerebellopontine angle (CPA) are uncommon and comprise less than 1% of CPA tumors. Primary extra-axial pilocytic astrocytoma of the CPA is very rare, with only four cases reported to date. Primary extra-axial pilocytic astrocytoma of CPA radiologically mimic other tumors such as vestibular schwannoma and meningioma. These tumors pose a formidable challenge from a neurosurgical perspective, and different strategies are required to protect surrounding neurovascular structures. Here, we are tempted to report an interesting case of primary extra-axial pilocytic astrocytoma of the cerebellopontine angle in a 10 year-old male child.
