FIG 7. Left sphenoid ridge meningioma in a 54-year-old woman.

A, Spin-echo T2-weighted image.

B, Superposed color image shows the meningioma with certain colors: the anterior and posterior parts appear violet, and the left and right parts are green, which can be interpreted (although it has not been confirmed histologically) to mean that this tumor, as a whole, has a radially oriented internal structure. The posterior limb of the left internal capsule (arrow) appears redder and thinner than the contralateral limb (arrowhead). This indicates that the tumor compresses the limb and deflects its direction vertically.
