Dysembryoplastic neuroepithelial tumors are rare benign brain tumors preferentially affecting epileptic children. The diagnosis is evoked by the association of clinico-radiological criteria: partial epilepsy beginning before the age of 20 years, absence of neurological deficit, cortical and temporal topography of the lesion and absence of mass effect or peri-lesional edema. The soap bubble appearance is a characteristic MRI sign of this tumor whose reference treatment is surgical excision allowing to palliate epileptic seizures in an efficient way.
