Pre-and post-contrast study.
Enhancing left cerebellopontine angle mass with broad dural base along the petrous ridge measures approximately 2.4 x 1.3 cm transaxially and is most consistent with a meningioma.
Minor adjacent dural tail to the anterior margin of the tentorium cerebelli and along the petroclinoid ligament.
No extension into the internal acoustic canal. No adjacent hyperostosis.
Mild lateral displacement and distortion of the pons and mild crowding of foramen Magnum without tonsillar herniation.
No other intra or extraaxial mass nor abnormal enhancement.
Conclusion: Left CPA/petrous ridge meningioma.
