E Posterior cerebral arteries
F Posterior inferior cerebellar artery
G Small vessel lacunar stroke
H Superior division of middle cerebral artery(dominant hemisphere)

Match the clinical syndrome with the site of arterial occlusion.

A 72-year-old man with gait apraxia and paralysis of the opposite foot and leg.

A man with sudden onset of bilateral complete visual loss. There are no abnormalities of the anterior chamber or retina and pupillary reaction to light is preserved.

A 69-year-old woman who develops contralateral hemisensory loss and describes severe burning pain in the affected area.

A 60-year-old who with a fluent dysphasia who is unable to comprehend instructions.

Ans:
Anterior cerebral artery
Posterior cerebral arteries
Thalamogeniculate artery
Inferior division of middle cerebral artery (dominant hemisphere)

Occlusion of the anterior cerebral artery affects the 'motor leg' area and the frontal cortex which results in weakness of the contralateral leg, foot and gait apraxia. Cortical blindness with preserved pupillary reflex results from bilateral infarction in the territory supplied by the distal posterior cerebral arteries. Patients are often unaware of the blindness (Anton's syndrome). Thalamic stroke results in contralateral hemisensory loss and severe burning pain responsive to tricyclics. Wernicke's aphasia results from occlusion of the inferior division of the middle cerebral artery which supplies the temporal cortex. Broca's non fluent aphasia, facial and hand weakness suggests occlusion of the superior division of the middle cerebral artery.
