Ganglioglioma mimicking transmantle focal cortical dysplasia in a two-year old child with intractable epilepsy

We report about a two year old girl with onset of severe temporo-parieto-occipital seizures at age of 7 month, retardation of speech development and ataxia. High resolution T2-weigthed MRI identified a hyperintense lesion arising from the ependyma of the right ventricle to the right superior temporal gyrus. In addition, T1-weighted MRI indicated a slightly hyperintense nodular area within this lesion as well as minute calcification. Neuroradiological inspection was highly compatible with a transmantle type of focal cortical dysplasia or cortical tuber (without further lesions of the tuberous sclerosis complex).…
