Patient has undergone a cervical duplex ultrasound scan and right-sided internal carotid artery atherosclerotic disease was identified.

Anterior choroidal artery syndrome is a rare entity characterized by the triad of:

• hemiplegia
• hemianaesthesia
• contralateral hemianopia

This is the result of the cerebral infarction in the anterior choroidal artery territory, which in this case the patient has. Anterior choroid artery vascular territory is divided into:

• cisternal segment
  • hippocampus and amygdala
  • optic tract
  • lateral geniculate nucleus and lateral aspect of the thalamus
  • posterior limb of the internal capsule
  • lateral aspect of the midbrain
• intraventricular segment
  • choroid plexus of the anterior part of the temporal horns of the lateral ventricles
