Heterogeneity of Aicardi syndrome

Two patients with suspected Aicardi syndrome are reported. One is an unusually mild case with partial expression of the syndrome without mental retardation. The second case has typical features of the syndrome. The authors emphasize the clinical heterogeneity of the syndrome with good prognosis of the first patient and indicate the superiority of magnetic resonance imaging in making an accurate diagnosis of the brain anomalies compared to computed tomography.
