Right middle cerebral
QuestionChoice
Middle cerebral artery strokes are more common than anterior cerebral artery strokes. Even though left anterior cerebral artery strokes affect the right side of the body, patients typically experience sensory loss and lower limb weakness.

d
Left anterior cerebral
QuestionChoice
Cerebellar strokes affect balance and coordination and there are no signs of ataxia or loss of coordination in this patient, making this option unlikely.

e
Left superior cerebellar stroke
QuestionChoice
It is less likely that this artery is affected because middle cerebral artery strokes are more common. If the anterior cerebral artery was affected then the patient would have experienced contralateral (left) sensory loss and lower limb weakness. This patient has weakness and sensory loss predominantly of the right upper limb.

c
Right anterior cerebral
QuestionChoice
This patient is experiencing sensory loss and weakness on his right side, therefore the artery that is affected is on the contralateral side (i.e. the left).
middle cerebral artery strokes typically spare the leg which is the case with this patient. Anterior cerebral artery strokes, however, present with contralateral sensory loss and lower limb weakness.

A 58-year-old man with a past medical history of Type 2 diabetes and hypertension presents to A&E with a sudden loss of sensation and weakness in his right arm. On examination, the power of his right arm is 1/5 on the MRC scale and the reflexes of the right arm are absent. The power and sensation of the right leg is preserved.

Which artery is most likely to have been affected?
