A 54-year-old man, with a twenty-five year history of poorly controlled type 2 diabetes mellitus, presented with 4 days of abnormal movements of the right side of face precipitated by tactile stimulus over his face, upper limbs and trunk. His physical examination revealed right hemifacial spasm precipitated by auditory and tactile stimulus, opsoclonus, blepharospasm, oromandibular dystonia, perioral tremor and myoclonic jerks involving the head and neck particularly triggered by neck extension (video 1,http://links.lww.com/CPJ/A222).
