title: [Lennox-Gastaut syndrome with band form heterotopia: a case report].
abstract: A 10-year-old girl with developmental delay, mental retardation and intractable seizures is reported. She manifested clinically as Lennox-Gastaut syndrome with unknown etiology before admission. Brain MRI revealed a band-like lesion over the bilateral subcortical region being later recognized as band-form heterotopia. This type of heterotopia may be overlooked easily due to its symmetrical distribution and mild degree of cortical convolutional anomaly. As it is often associated with intractable seizures and psychomotor retardation, the prognosis is poor. This patient responded poor to ketogenic diet and anticonvulsants. We present this case and review the related articles.
