title: Ictal barking as a manifestation of temporal lobe epilepsy.
abstract: Ictal nonspeech vocalizations have been described as manifestations of either frontal or temporal epileptogenicity originating mainly from the dominant hemisphere. Ictal barking, particularly, has been considered a manifestation of mesial frontal epilepsy. A 42-year-old right-handed male with posttraumatic drug-resistant complex partial epilepsy manifested ictal barking near electrographic onset. Extraoperative electrocorticography with subdural electrode coverage of the right frontoparietal and temporal and left frontal surfaces provided surveillance of ictal origin and propagation. Ictal origin was identified in the right mesial temporal lobe with barking vocalization manifesting within 3s of electrographic onset. No subsequent spread of activity was noted beyond the temporal lobe. Resection of the mesial temporal structure resulted in seizure freedom. Pathology identified hippocampal sclerosis. This case supports the notion that an intrinsic, intralobar epileptogenic neural network in either hemisphere can act as a conduit into the limbic and memory circuits without a laterality bias to manifest as barking.
