Summary
Thalamic hemorrhage can cause tremors, a rare complication. This case study details a patient experiencing tremors due to thalamic bleeding, with eventual resolution linked to a later ischemic stroke.
Area of Science:
- Neurology
- Neuroscience
- Medical Imaging
Background:
- Thalamic hemorrhage is an uncommon cause of tremors.
- Delayed rubral tremor is a rare complication of thalamic hemorrhage.
Observation:
- A patient presented with a combined resting-postural-kinetic tremor secondary to thalamic hemorrhage.
- Magnetic resonance imaging revealed subthalamic involvement but no mesencephalic lesion.
Findings:
- The patient experienced significant tremor suppression five years post-stroke.
- This suppression was likely associated with a subsequent ischemic capsular lesion.
Implications:
- Lesions proximal to the rubral and nigral outflow systems can induce involuntary movements mimicking rubral tremor.
- This highlights the complex pathways involved in tremor generation and resolution.
