LIBERALESSO, Paulo Breno Noronha et al. Late-onset childhood occipital epilepsy. An unusual case in adolescence and differential diagnosis with migraine. J. epilepsy clin. neurophysiol. [online]. 2009, vol.15, n.1, pp.37-40. ISSN 1676-2649. http://dx.doi.org/10.1590/S1676-26492009000100008.
INTRODUCTION: The new proposed classification of ILAE Task Force (2001) proposes that the occipital epilepsies should be split into two subtypes: an early-onset benign childhood occipital epilepsy (or Panayiotopoulos type) and late-onset childhood occipital epilepsy (or Gastaut type). Migraine with visual aura must be considered as a differential diagnosis in childhood and adolescents with occipital epilepsy without motor phenomena. OBJECTIVE: The goal of our paper is to report the case a 16-year-old female, with normal psychomotor development, that during the lunch time presented an event characterized by the vision of multiple colored spots which were moving horizontally and vertically and also in circles through the visual field. Minutes after the visual event, the patient referred to a severe diffuse throbbing headache with frontal predominance. During the clinical investigation was submitted to a video-electroencephalogram exam for 12 hours with, reveling occipital sharp-waves discharges in occipital right region as well as in occipital left region. CONCLUSION: We reported of such classic type of epileptic syndrome in a patient in the unusual age of onset, the end of adolescence, considering the differential diagnosis with migraine with visual aura.
