Summary

Cerebellar infarcts, often missed, present with symptoms like vertigo and ataxia. Full territory infarcts can be severe, while partial ones usually lead to good recovery.

Area of Science:

  • Neurology
  • Neuroradiology
  • Vascular Neurology

Context:

  • Cerebellar infarcts, previously underdiagnosed, are now well-visualized with CT and MRI.
  • Infarcts can affect the full or partial territory of a cerebellar artery, impacting prognosis and management.
  • Clinical presentation often includes vertigo, ataxia, and dysarthria, with variations based on the affected artery.

Purpose:

  • To differentiate between full and partial territory cerebellar infarcts based on imaging findings and clinical outcomes.
  • To elucidate the common causes, including cardioembolism and atherosclerosis, and less frequent etiologies like dissection.
  • To describe the characteristics and clinical course of border zone cerebellar infarcts.

Summary:

  • Full territory cerebellar infarcts may cause brainstem compression and hydrocephalus, sometimes necessitating emergency surgery.
  • Partial territory infarcts are more common, typically have a benign outcome with full recovery, and present without drowsiness.
  • Border zone infarcts, occurring in one-third of cases, share symptoms with territorial infarcts but may feature delayed postural symptoms.

Impact:

  • Improved diagnostic accuracy and understanding of cerebellar infarcts through advanced imaging techniques.
  • Highlights the importance of identifying the infarct territory and cause for appropriate patient management.
  • Provides a comprehensive overview of cerebellar infarcts, aiding clinicians in diagnosis, prognosis, and treatment strategies.
