(c) T2WI MRI before treatment showing hyperintensity of the soft tissues, which were permeated by massive flow voids representing enlarged feeding and draining vessels. (d) Six months after the final session, fat-suppressed T2WI showing regression of the soft tissue swelling and disappearance of the flow voids
