Small well-defined extra-axial broad-based mass In the right cerebellopontine angle at the anterior margin of the porus acusticus internus with adjacent hyperostosis. It elicits isosignal to the cortical grey matter on both T1, T2, and FLAIR with vivid homogeneous enhancement on postcontrast sequences. No significant mass effect on the adjacent facial nerve/vestibulocochlear nerves or cisternal segment of the trigeminal nerve.
Empty sella.
Mild cerebral volume loss.
