Reduction by 98% in uterine myoma volume associated with significant symptom relief after peripheral treatment with magnetic resonance imaging-guided focused ultrasound surgery.

Magnetic resonance imaging-guided focused ultrasound surgery is a noninvasive treatment for symptomatic uterine myomas. Previous studies have demonstrated a correlation between the treated volume of the myoma, improvement in symptoms, and lesion shrinkage. We report a case in which MRgFUS treatment only at the periphery of the myoma resulted in a 98% reduction in tumor volume at 8 months posttreatment, and at 12-month follow-up, only a small lesion was visible at magnetic resonance imaging.
