Hypertensive putaminal hemorrhage presenting with hemichorea.
Stroke
|January 1, 1985
Summary
A hypertensive man developed hemichorea due to a putaminal hemorrhage. This case highlights a rare presentation of motor deficit linked to basal ganglia lesions.
Area of Science:
- Neurology
- Neuroimaging
- Movement Disorders
Background:
- Hemichorea is a rare neurological disorder characterized by involuntary, purposeless, and rapid movements of one side of the body.
- It is often associated with lesions in the basal ganglia, particularly the contralateral putamen or caudate nucleus.
- Hypertension is a common comorbidity in patients presenting with cerebrovascular events.
Observation:
- A 42-year-old male patient with a history of hypertension presented with progressive motor deficits.
- The primary manifestation was hemichorea, affecting one side of his body.
- Computed Tomography (CT) imaging revealed a hemorrhage in the contralateral putamen.
Findings:
- The patient's hemichorea was directly attributed to a putaminal hemorrhage.
- Unlike previously documented cases involving nonhemorrhagic lesions, this instance involved an acute bleed.
- The clinical course of the patient was benign, with resolution of symptoms.
Implications:
- This case expands the spectrum of basal ganglia lesions associated with hemichorea, including hemorrhagic lesions.
- It underscores the importance of neuroimaging, specifically CT scans, in diagnosing the etiology of acute hemichorea.
- Understanding these associations aids in predicting patient outcomes and guiding treatment strategies for movement disorders.
