A 44-year-old female is described who developed persistent upper extremity
and orolingual dystonia several weeks after suspected onset of central
pontine myelinolysis (CPM), later confirmed by characteristic pontine
lesions on MRI. No foci of the extrapontine myelinolysis were evident. This
case confirms that dystonia may be a late and persistent sequela of CPM and
may occur in the absence of visible lesions outside the brainstem.
