OBJECTIVE: Convergence spasm is a clinical condition characterized by transient episodes of convergence, miosis and accommodation with strabismus and diplopia and it is usually a manifestation of a functional neurological disorder. We describe a patient with a challenging diagnosis of convergence spasm in the setting of occipital lobe epilepsy. CASE REPORT: A 52-year-old woman came for the assessment of focal epilepsy due to left occipital cortical dysplasia. During ocular motility tests, she presented with episodes of short duration (∼10-30 seconds) of convergent strabismus. Neuropsychological evaluation showed a severe mixed anxiety-depressive disorder with a tendency toward somatization. RESULTS: Convergence spasm was recorded during video-EEG examination and no ictal activity was present. CONCLUSIONS: To our knowledge, no other report of functional convergence spasm in the context of focal epilepsy associated with cortical dysplasia has been described in literature.

Abstract

OBJECTIVE: Convergence spasm is a clinical condition characterized by transient episodes of convergence, miosis and accommodation with strabismus and diplopia and it is usually a manifestation of a functional neurological disorder. We describe a patient with a challenging diagnosis of convergence spasm in the setting of occipital lobe epilepsy. CASE REPORT: A 52-year-old woman came for the assessment of focal epilepsy due to left occipital cortical dysplasia. During ocular motility tests, she presented with episodes of short duration (∼10-30 seconds) of convergent strabismus. Neuropsychological evaluation showed a severe mixed anxiety-depressive disorder with a tendency toward somatization. RESULTS: Convergence spasm was recorded during video-EEG examination and no ictal activity was present. CONCLUSIONS: To our knowledge, no other report of functional convergence spasm in the context of focal epilepsy associated with cortical dysplasia has been described in literature.
