These are mostly supratentorial tumors with rare cases of extra-axial spread. Even rarer is the presentation of glioblastoma within the cerebellopontine angle (CPA). Here, we present a case of a previously resected and irradiated glioblastoma metastasizing from the right temporal lobe region to the contralateral CPA. Case Description: A 24-year-old female who previously underwent surgery and concurrent chemoradiotherapy for a right temporal glioblastoma in August 2020, presented to us 6 months later with headaches, vomiting, and dizziness for the past 6 days. She had left-sided dysmetria on examination. MRI of the brain showed an extra-axial, heterogeneously enhancing lesion within the left CPA. The patient subsequently underwent a left retrosigmoid craniotomy and maximum safe resection of the lesion. Histopathology reported the lesion as a glioblastoma. Conclusion: Glioblastoma within the CPA is rarely reported within the literature. To date, our case is the first instance of an extra-axial contralateral metastasis of glioblastoma.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/c477bb69-d5fe-4895-89f0-5f2057db8763/featured/hero-1781561808184.png","publishDate":"2021-11-30T00:00:00.000Z","doi":"10.25259/SNI_684_2021","categories":["Unique Case Observations","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2021/11/11255/SNI-12-586.pdf"}
