Degenerative anterior biopercular syndrome initially misdiagnosed as a psychogenic disorder.

摘要

The anterior biopercular syndrome or Foix-Chavany-Marie syndrome (FCMS) originally described in 1926 is denned by diminished or absent voluntary control of facial, pha-ryngeal, lingual, and masticatory muscles while refiectory movements are preserved [2, 8], In the original description, the syndrome occurred after bilateral damage of the anterior opercular area surrounding the insula caused by stroke. Other causes of the syndrome are infections of the nervous system, cortical dysplasias, tumors, trauma, and, but exceedingly rare, degenerative disease [4, 7, 8].
