Summary
Rarely, damage outside the corpus Luysii can cause hemiballism. This case shows hemiballism from a stroke affecting the caudate nucleus and putamen, impacting regulatory activity.
Area of Science:
- Neuroscience
- Neurology
- Cerebrovascular Diseases
Background:
- Hemiballism is a rare hyperkinetic movement disorder.
- Typically associated with lesions in the subthalamic nucleus (corpus Luysii).
- Other brain structures can rarely be implicated.
Observation:
- A case of hemiballism is presented.
- The patient experienced involuntary, violent, and random movements.
- Imaging revealed infarction in the lenticulo-striatal artery territory.
Findings:
- Computed tomography (CT) and magnetic resonance (MR) imaging identified lesions.
- Lesions were located in the caudate nucleus and putamen.
- This suggests the caudate nucleus's regulatory function on the pallidum was suppressed.
Implications:
- This case expands the understanding of hemiballism etiology.
- Highlights the role of the basal ganglia, beyond the corpus Luysii, in movement control.
- Demonstrates the utility of advanced neuroimaging in diagnosing rare movement disorders.
