Occlusion Of Cerebral Vessels

Front 1

Middle Cerebral Artery

Back 1

Contralateral face and arm paralysis and sensory loss; possible aphasia (temporal lobe) or contralateral neglect (parietal lobe); hemianopsia or quadrantopia if damage to optic radiation

Front 2

Posterior Cerebral Artery

Back 2

homonymous hemianopsia of contralateral visual field, often w/ macular sparing (PCA compression may be result of uncal herniation)

Front 3

AICA

Front 4

PICA

Back 4

Lateral Medullary Syndrome
Contralateral pain and temp loss over body (spinothalamic tract); ipsilateral dysphagia, hoarseness, no gag reflex (IX and X); vertigo, diplopia, nystagmus, vomiting (vestibular dysfn); ipsilateral Horner's syndrome; ipsilateral loss of pain and temp sensation over face (spinal tract and nucleus of V)
