1) T1-weighted MRI post-Gadolinium demonstrates an extra-axial mass consistent with a meningioma.
2) RGB color map.
3) RGB color map, co-registered with a weighted RM T1 3D Gradient Echo demonstrates mass effect and distortion of the right corticospinal tract (red), which appears displaced but not interrupted.
4) Video 3D - The spatial relationship between the right corticospinal tract and the meningioma (RGB Color map, + FLAIR + FTT).
The right corticospinal tract was reconstructed using the red color; the left corticospinal tract was reconstructed using the green color.
