Figure 2

MRI images of a 22-year-old Asian male, presenting with blurred vision, headache, tinnitus, numbness of face, and left hemiplegia. (a) A large macrolobulated extra-axial mass arising from the dura in the supratentorial convexity. The mass has an intermediate signal similar to the brain on T1. (b) The mass demonstrates a heterogeneous “yin yang” appearance of low and high signal intensity on T2. (c) Diffuse contrast enhancement is seen and a (d) dural tail (red arrow) is present. (e, f) Areas of restricted diffusion are seen on diffusion-weighted imaging (DWI).
