Correct answer: A — Left lateral-medullary infarction in vertebral or PICA territory

The best answer is “Left lateral-medullary infarction in vertebral or PICA territory”. UK stroke guidance supports urgent vascular imaging and reperfusion selection, short-course dual antiplatelet therapy for eligible minor stroke or high-risk TIA, decompression for life-threatening swelling, and secondary prevention matched to mechanism. The alternatives “Left medial medulla supplied by anterior spinal branches”, “Right lateral pons supplied by anterior inferior cerebellar branches”, “Left cerebellar hemisphere supplied by superior cerebellar branches”, “Right thalamus supplied by posterior cerebral perforators” are clinically adjacent possibilities, but they do not match the defining chronology, localisation, physiology, investigation result or UK management sequence in this stem.
