Abstract

Insular lobe seizure (ILS) is very rare and ictal focus has not been documented by neuroimaging studies. Clinical characteristics consist of clearly preserved consciousness, visceral sensation, somatomotor symptoms, and dysphonic or dysarthric speech. We report a 34-year-old female with ILS, manifesting as first onset status epilepticus. SISCOM and SPM analysis through brain MRI and 18F FDG PET-CT reveals ictal focus on the bilateral claustrum, which has a close relationship with insula anatomically. This is the first case report in Korea.KeyWords:Insular lobe seizure, Claustrum, Neuroimages
