Multiple acute infarcts in the posterior circulation often affect the cerebellum. Clinical suspicion is key when both supratentorial and infratentorial infarcts occur, guiding diagnosis of posterior circulation stroke.

Area of Science:

  • Neurology
  • Radiology
  • Vascular Medicine

Background:

  • Posterior circulation strokes present unique diagnostic challenges.
  • Multiple acute infarcts in distinct arterial territories of the posterior circulation are not well-characterized.

Purpose of the Study:

  • To evaluate the clinical, radiological, and prognostic features of patients experiencing multiple acute infarcts within the posterior circulation.

Main Methods:

  • Analysis of data from a prospective acute stroke registry.
  • Utilized magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) for diagnosis.

Main Results:

  • 11% of posterior circulation stroke patients (27/236) had multiple infarcts.
  • Common patterns included infratentorial and supratentorial infarcts; brainstem involvement occurred in 7 patients.

  • Outcomes were linked to infarct size, not the number of infarcts, with >25% dependency or death at one month.

    • Conclusions:

    • Multiple posterior circulation infarcts typically involve the cerebellum.
    • Simultaneous brainstem and posterior cerebral artery territory infarcts without cerebellar involvement are rare.
    • Clinical presentation, particularly coexisting supratentorial and infratentorial infarcts, can suggest this condition prior to imaging.
