Dysembryoplastic Neuroepithelial Tumor (DNET) causing Refractory Focal Seizures


Dysembryoplastic neuroepithelial tumor (DNET) is relatively uncommon benign tumor, responsible for causing partial seizures in children, many of those cases may be medically refractory. The most common location is temporal lobe, as in this case (about 65% of cases). About 20% cases involve frontal lobe. The remainder of cases involve caudate nucleus, cerebellum and pons.Continue reading “Dysembryoplastic Neuroepithelial Tumor (DNET) causing Refractory Focal Seizures”

CAVERNOMA Causing Chronic Focal Epilepsy


FLAIR MRI images shows a left frontal hypointense lesion with multiple flow voids, surrounded by hyperintense areas, suggestive of a cavernoma with surrounding gliosis. The patient had a history of right focal motor seizures (with or without secondary generalization) of 5 years duration, which was well controlled with medications (oxcarbazepine, sodium valproate and clobazam). Therefore,Continue reading “CAVERNOMA Causing Chronic Focal Epilepsy”
