[Epileptic seizures, hemiplegia and hyperglycemia: late discovery of a localized cortical dysplasia].
A 56-year-old woman was hospitalized with a right hemiplegia and aphasia evoking a cerebral infarction. In fact the neurologic deficits were of post-ictal origin, secondary to a partial epilepsy which began a few weeks before, at the same time as a polyuria-polydipsia syndrome revealing diabetes mellitus. This case illustrates the possibility for a partial epilepsy to occur in relation with a nonketotic hyperglycemia. If in most of those cases there is no underlying cortical lesion, in some observations the hyperglycemia is associated with an infarction. In our case the MRI revealed another type of lesion: a cortical dysplasia in form of a unilateral micropolygyria with a perisylvian distribution centered around the insula. The discovery of a cortical dysplasia at such an age is very unusual.
