Figure 15: Median nerve neurofibroma. (a-c) TSE T2 W axial fat suppressed images show normal caliber of the median nerve both proximal and distal to the site of lesion; (b) TSE T2 W axial fat suppressed images at the site of lesion showing marked T2 hyperintensity with swelling of the median nerve (arrow) in the distal forearm. No separate nerve fascicle is visualized at this level. (d) PD VISTA axial image showing the lesion to be hyperintense. (e) SE T1 W image shows a large T1 iso to mildly hyperintense fusiform mass (arrow) arising from the median nerve. (f) STIR thin coronal image demonstrating a fusiform neurofibroma of the median nerve (arrow)
