His neurological examination revealed significant aphasia, left third nerve palsy, right homonymous hemianopsia, and right-sided hemiplegia with hemisensory deficits. A brain magnetic resonance image showed an acute ischemic infarct in the left middle cerebral artery distribution without mass effect.
