Figure 2. Axial T₁ weighted MRI at the level of the Pons. The mass is isointense to hypointense to brain on T₁ weighted image (a). On T₂ weighted image mixed signal intensity, composed of an isointense solid portion and a hyperintense cystic portion compared with brain was noted (b). The lesion enhances homogeneously after intravenous administration of contrast media (c). The midbrain is displaced medially and deformed. Wedge-shaped dural enhancement (arrow) which tapers backward is seen on the contrast-enhanced T₁ weighted sagittal image (d).
