This case had an elderly patient with sudden onset visual change and an underlying infarct in the left occipital region. The The mild symptoms of dizziness and uncoordinationincoordination can be part of visual disturbance but are also controlled by a similar blood supply (the brain stem and cerebellum are posterior circulation structures). Further investigation of this patient with cardiac work upworkup and vessel imaging may be of benefit. Treatment for this is as for other strokes, and thrombolysis is time dependent-dependent.

Answer
was changed:
With the acute onset and localising signs, a "posterior circulation" infarct is likely. Other diagnoses to consider include migraine aura, vertebral dissection or a space occupying-occupying lesion in or near the cerebellum.

The hypodense area is supplied by the left posterior cerebral artery (PCA). This is a left PCA territory infarct.
