CME Credits: 1.00

A 62-year-old man with diabetes and hypertension with history of left putaminal hemorrhage and right hemiparesis 1.5 years ago presented to our movement disorders clinic with progressive dystonia and spasticity of the right upper and lower limbs for 8 months. The patient noticed that whenever he tried to hold a pen or a spoon with his right hand mainly using the thumb and index finger, he had involuntary opening of his mouth, which subsided on resting the hand. This was described as a jaw-opening oromandibular dystonia (OMD) overflowing from the hand dystonia. Chewing movements made by the patient led to the exacerbation of dystonia in the right hand (). Magnetic resonance imaging revealed slitlike encephalomalacic focus with hemosiderin deposition in left basal ganglia denoting sequelae of hemorrhage (). The patient was treated with oral antidystonia treatment with trihexyphenydyl, clonazepam, and baclofen and later with botulinum toxin for the hand dystonia and showed some improvement in symptoms.
