Summary
Magnetic resonance-guided focused ultrasound thalamotomy (MR-FUS) for essential tremor (ET) can rarely cause chorea. This side effect may occur when the lesion extends to the subthalamic nucleus (STN), disrupting the brain's indirect pathway.
Area of Science:
- Neurology
- Neurosurgery
- Medical Imaging
Background:
- Magnetic resonance-guided focused ultrasound thalamotomy (MR-FUS) is an emerging noninvasive treatment for essential tremor (ET).
- The procedure is generally well-tolerated, with common side effects including sensory disturbances and gait issues.
