Anarthria and bilateral central faciolinguopharyngeomasticatory paralysis with automatic voluntary dissociation are the clinical hallmarks of Foix-Chavany-Marie syndrome (FCMS), the cortico-subcortial type of suprabulbar palsy. We present a 64-year-old man who was admitted due to acute onset of speechlessness for days. Neurological examinations demonstrated typical features of FCMS. Cranial MRI showed a right opercular lesion and several lacunar infarcts in bilateral hemispheres. Hexamethylpropylenamine oxime (HMPAO) brain SPECT revealed hypoperfusion in bilateral opercular regions and notably on the right side. In review of previous reports, the most common etiology of FCMS is stroke in the region of either operculum. Our case may be a good example of FCMS after multiple cerebrovascular insults over bilateral opercular cortico-subcortical areas as demonstrated in MRI and SPECT studies.

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.

Foix-Chavany-Marie syndrome (FCMS) presents with anarthria and bilateral (B/L) central facio-linguo-velo-pharyngo-masticatory paralysis with "autonomic voluntary dissociation." The most common cause of FCMS is cerebrovascular disease, while rarer causes include central nervous system infection, developmental disorders, epilepsy, and neurodegenerative disorders. Even though this syndrome is also referred to as (B/L) anterior operculum syndrome, patients with lesion in sites other than (B/L) opercular regions also can develop the syndrome.
