Magnetic Resonance Image Guided Focused Ultrasound Thalamotomy for Essential Tremor in a Patient with an Arteriovenous Malformation

Key Points

This report examines the feasibility of MRgFUS thalamotomy for essential tremor in a patient with a concurrent arteriovenous malformation.
Patient underwent workup including contrast-enhanced brain MRI that revealed an incidental arteriovenous malformation.
MRgFUS therapy was considered despite the AVM, designated as a no pass zone for safety.
MRgFUS effectively utilized for essential tremor despite the presence of an AVM.
Patient elected to proceed with tremor treatment without addressing the AVM.

Abstract

Background: Magnetic Resonance Guided Focused Ultrasound Thalamotomy (MRgFUS) is a non-surgical treatment option for medically refractory Essential Tremor (ET) or tremor dominant Parkinson’s Disease. Case Report: A 75-year-old left-handed man with medically refractory essential tremor presented for MRgFUS evaluation. During workup, contrast-enhanced brain MRI revealed an incidental right frontal arteriovenous malformation. After discussion of management options, the patient elected not to pursue treatment of the newly diagnosed AVM and proceeded with tremor-focused therapy. Discussion: It is possible to effectively utilize MRgFUS for treatment of tremors in carefully selected patients with cerebral AVMs by designating the malformation as a no pass zone.
