Symptomatic occipital epilepsy misdiagnosed as migraine.

Two young patients with symptomatic occipital lobe epilepsy due to discrete lesions of cysticercosis were misdiagnosed and treated for 2 years as migraine with visual aura. The patients suffered from frequent visual seizures often followed by migraine-like headache. Seizures manifested with colored and mainly circular elementary visual hallucinations of up to 1 minute duration. Headache, often severe and of long duration, was frequently associated with nausea, photophobia, and phonophobia. Both patients became seizure-free with appropriate treatment of the underlying disease and epileptic seizures.
