Unilateral Anterior Opercular Syndrome, Due to Cardio-Embolic Stroke: Case Report
Abstract: This study describes a rare case of anterior opercular syndrome (AOS), a cortical form of pseudobulbar paralysis characterized by facio-labio-glosso-pharyngo-laryngeal dysfunction with autonomic-voluntary dissociation. A 74-year-old male presented with acute dysphagia, anarthria, and bilateral facial weakness. Comprehensive clinical, neuroimaging, electrophysiological, and cerebrospinal fluid assessments were conducted, followed by a three-year follow-up. Imaging revealed a unilateral opercular infarction associated with contralateral white matter changes, consistent with a cardio-embolic etiology due to atrial fibrillation. Management included anticoagulation therapy and enteral nutrition via percutaneous endoscopic gastrostomy. Gradual functional improvement was observed over time. This case highlights the diagnostic importance of autonomic-voluntary dissociation and neuroimaging in AOS and emphasizes the need for appropriate secondary stroke prevention strategies.
