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.
