Foix-Chavany-Marie syndrome due to unilateral opercular infarction-A case report.

KEY CLINICAL MESSAGE: Unilateral opercular lesions can result in Foix-Chavany-Marie syndrome, which is marked by acute anarthria, automatic-voluntary movement dissociation-most notably the absence of voluntary facial and tongue movements-and a generally better prognosis. Better patient outcomes are mostly dependent on early detection, management, and rehabilitation.

ABSTRACT: Opercular syndrome is a rare neurological disorder caused by bilateral or unilateral lesions of the operculum that result in symptoms related to speech and swallowing difficulties with dissociation of automatic-voluntary movements in affected muscles. 78-year-old female presented with acute onset dysarthria, left sided facial deviation and difficulties in chewing, speaking, and swallowing. CT head revealed ischemic changes in left frontal operculum and was diagnosed with the unilateral opercular syndrome. The case was managed according to ischemic stroke protocol. The patient was discharged after 7 days of hospital stay, with MRS 2, NIHSS 9 and secondary stroke preventive measures. At 4 months follow-up, her MRS was 1, with mild dysarthria, that could be understood, and her swallowing improved to some amount of drooling while feeding. Early recognition, treatment, and rehabilitation play important role in prompt improvement of symptoms.
