Summary

Imaging studies can detect lesions causing hemiballismus. Magnetic resonance imaging (MRI) is superior to computed tomography (CT) for identifying these causative lesions, particularly small ones.

Area of Science:

  • Neurology
  • Radiology
  • Neuroimaging

Background:

  • Hemiballismus is a hyperkinetic movement disorder characterized by involuntary, violent, and random-arm-like movements.
  • Identifying the underlying lesion is crucial for diagnosis and management.

Purpose of the Study:

  • To determine the frequency of detecting hemiballismus-causing lesions on CT and MR imaging.
  • To compare the efficacy of CT and MRI in identifying these lesions.

Main Methods:

  • Retrospective review of CT and MR examinations in six patients with hemiballismus.
  • Analysis of lesion detection rates across different imaging modalities (CT and MRI).
  • Consideration of various potential lesion locations, including the subthalamic nucleus, putamen, and thalamus.

Main Results:

  • A causative lesion was identified in five out of six patients.
  • MRI detected responsible lesions in all five patients who underwent the examination.
  • CT identified a lesion in only one of the two patients who underwent CT alone.
  • Common causes included infarction, hemorrhage, trauma, and abscess.

Conclusions:

  • Cross-sectional imaging can generally detect lesions responsible for hemiballismus.
  • MRI's multiplanar capabilities offer superior sensitivity for detecting small lesions in critical locations.
  • MRI is the preferred imaging modality for patients with hemiballismus.
