Abstract
<strong>Background:</strong> We present the case of a 65-year-old female with sudden-onset involuntary mouth opening, deviation of the jaw, facial grimacing, and tongue movements that started 6 months prior to her admission. <strong>Case Report:</strong> She was diagnosed with oromandibular dystonia. Differential diagnosis of oromandibular dystonia and various etiologies were investigated. Neuroimaging studies revealed a left cerebellar infarction. <strong>Discussion:</strong> To our knowledge, this case is the first oromandibular dystonia presenting with cerebellar ischemic stroke. Possible roles of the cerebellum for the pathophysiology of oromandibular dystonia are discussed.
Highlights
Oromandibular dystonia (OMD) is a cranial segmental dystonia of the lips, jaw, and tongue, causing involuntary mouth closure or opening, deviation of the jaw, tongue movements, or any combination of these due to repetitive or sustained spasms of masticatory, facial, or lingual muscles
Other types of dystonia associated with cerebellar disease are known,[3,4,5] but reports of OMD related to cerebellar stroke are rare.[6]
We present a case of OMD following a cerebellar ischemic stroke
Summary
Oromandibular dystonia (OMD) is a cranial segmental dystonia of the lips, jaw, and tongue, causing involuntary mouth closure or opening, deviation of the jaw, tongue movements, or any combination of these due to repetitive or sustained spasms of masticatory, facial, or lingual muscles. OMD is the most frequent cranial dystonia after blepharospasm[1] and can occur in isolation or appear together with other forms of craniocervical dystonia.[2] drug-induced, postanoxic, neurodegenerative disorder-associated, and head injuryassociated etiologies have been reported, the cause of OMD is unknown in the majority of patients. Other types of dystonia associated with cerebellar disease are known,[3,4,5] but reports of OMD related to cerebellar stroke are rare.[6] We present a case of OMD following a cerebellar ischemic stroke
