Isolated lateropulsion of the trunk in cerebellar infarct
Abstract:
MRI in a 63-year-old male with isolated lateropulsion of the trunk disclosed an infarct in the inferior portion of the right cerebellar hemisphere, suggesting an end-zone type infarct in the lateral branch of the right posterior inferior cerebellar artery (1PICA) or a borderzone infarct between 1PICA and superior cerebellar artery. A close clinico-topographical relationship between isolated lateropulsion of the trunk and lesion in the territory of 1PICA was demonstrated.
Insights
Isolated trunk lateropulsion in a 63-year-old male was linked to a cerebellar infarct. This finding highlights a connection between lesions in the right posterior inferior cerebellar artery territory and trunk lateropulsion.
Area of Science:
- Neurology
- Neuroimaging
- Cerebrovascular Diseases
Background:
- Lateropulsion of the trunk is a neurological symptom characterized by involuntary leaning or falling to one side.
- The cerebellum plays a crucial role in balance and posture control.
Observation:
- A 63-year-old male presented with isolated lateropulsion of the trunk.
- Magnetic Resonance Imaging (MRI) revealed an infarct in the inferior right cerebellar hemisphere.
Findings:
- The infarct was suggested to be an end-zone infarct in the lateral branch of the right posterior inferior cerebellar artery (1PICA) or a borderzone infarct.
- A strong clinico-topographical correlation was observed between isolated trunk lateropulsion and lesions within the 1PICA territory.
Implications:
- This study demonstrates a specific relationship between cerebellar infarcts in the 1PICA territory and trunk lateropulsion.
- Findings may aid in diagnosing the cause of lateropulsion and understanding cerebellar stroke syndromes.
