Funduscopic examination, according to the authors, revealed bilateral colobomatous discs. However, careful evaluation of the printed fundus photographs does not show optic disc colobomas but, rather, bilateral optic disc dysplasia and atypical peripapillary pigmentary changes. Moreover, the typical punched-out chorioretinal lesions were not present. These "punched-out" lesions are thought to be diagnostic of Aicardi's syndrome.2 Also, the electroencephalogram (EEG) in the case did not show a pure hypsarrhythmia, highly characteristic of the Aicardi syndrome,3,4 but a "pattern akin to it."Corpus callosum agenesis, arachnoidal cysts, and other neuroradiological midline anomalies have been described in patients with a
