Fig 1. A, Unenhanced CT image demonstrates a 2.4 x 3.8-cm hyperattenuated, well-circumscribed, extra-axial mass centered on the right tentorium.

B, Precontrast axial T1-weighted MR image reveals a heterogeneously hyperintense mass with a broad tentorial attachment.

C, Postcontrast coronal T1-weighted image reveals a homogeneously enhancing mass demonstrating a smooth lobular contour, with both infratentorial and supratentorial components.

D, Hyperintense signal intensity on DWI is seen within the medial aspect of the lesion.
