Fragile X syndrome (Fra-X) is a common cause of mental retardation that can be associated with partial epilepsy characterized by a variety of electro-clinical features. A wide spectrum of interictal activities are reported, although no data regarding ictal EEG activity have as yet been published. Drug-resistant seizures are uncommon, and the occurrence of clustering seizures or status epilepticus has only been reported anecdotally. We describe a Fra-X patient with refractory partial epilepsy related to a malformation of cortical development who experienced a partial status epilepticus that was well documented by video-EEG and MRI. We report the electro-clinical features and peri-ictal neuroimaging data.
