Sagittal spoiled gradient echo fat-saturated postcontrast images a before and b immediately following MRgFUS treatment in a 14-year-old girl. The pretreatment image clearly demonstrates the sciatic nerve coursing through the posterior aspect of the mass (black arrows). Post-treatment plane demonstrates large non-perfused volume with relative sparing of the region immediately adjacent to the nerve (white arrows)
