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.[1]
