Epileptic visual auras are elementary to complex and sometimes occur as colourful visual phenomena located close to or within the central part of the contralateral hemi-field. They typically last from seconds to a few minutes, which discriminates them from the usually longer-lasting visual auras (5-30 minutes) of patients suffering from migraine. We present an adult patient with occipital lobe epilepsy whose visual aura under epilepsy monitoring lasted for more than 30 minutes with almost no propagation, demonstrating a rare, but remarkable, sustained local epileptic network activity associated with resection of an occipital arterio-venous malformation.
