Posterior circulation infarct

A Posterior Circulation Infarct (POCI) is a type of cerebral infarction affecting the posterior circulation supplying one side of the brain.

Posterior Circulation Stroke Syndrome (POCS) refers to the symptoms of a patient who clinically appears to have had a posterior circulation infarct, but who has not yet had any diagnostic imaging (e.g. CT Scan) to confirm the diagnosis.

It can cause the following symptoms:

  • Cranial nerve palsy AND contralateral motor/sensory defect
  • Bilateral motor or sensory defect
  • Eye movement problems (e.g.nystagmus)
  • Cerebellar dysfunction
  • Isolated homonymous hemianopia

    • It has also been associated with deafness.
