ABSTRACT
Neurological examination showed mild blepharospasm, and involuntary contractions of perioral and jaw-opening muscles including the submentalis complex and the platysma during speaking. The remainder of the neurological examination was normal. Cranial magnetic resonance imaging (MRI) was normal except for a slight hyperintensity between the right putamen and external capsule. Further diagnostic work-up was normal including ceruloplasmin and urine copper, as well as routine laboratory diagnostics, cerebrospinal fluid analysis, electroencephalography (EEG), motor-and somatosensory-evoked potentials, and X-ray of the maxillary joint.
