Unlabeled images, for comparison: T2-weighted MR in the coronal plane with fat saturation

yellow-clavicle; green-brachial plexus; red-subclavian artery; blue-subclavian vein; orange-anterior scalene muscle; purple-middle scalene muscle

This is a coronal T2-weighted image sequence with fat saturation. There is an oval mass involving the right C6 nerve in the region of the brachial plexus which was found to be a schwannoma at surgery.
