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
Vertigo

It has also been associated with deafness.^[1]
