Abstract:
A 61-year-old man developed progressive weakness, numbness, and exercise-induced vascular symptoms in the left hand. There was left thenar wasting. The presence of a supraclavicular bruit and vascular studies indicated left subclavian artery stenosis, but electrophysiological studies demonstrated no evidence for brachial plexopathy. Subsequent neuroimaging studies revealed multifocal right cerebral infarction. Focal atrophy and weakness from a cerebral lesion can simulate a branchial plexus lesion.
