Internal carotid artery dissection commonly affects younger patients. We present a case of a previously fit and well 43-year-old gentleman who presented with a sudden onset of slurring of speech, with right-sided tongue deviation and fasciculation on examination. Signs and symptoms began following participation in a home workout class. Magnetic resonance angiography revealed right-sided extracrainal internal carotid artery dissection leading to right-sided unilateral twelfth cranial nerve palsy.
