[11C]-Methionine PET: dysembryoplastic neuroepithelial tumours compared with other epileptogenic brain neoplasms.
BACKGROUND AND OBJECTIVES Brain tumours responsible for longstanding partial epilepsy are characterised by a high prevalence of dysembryoplastic neuroepithelial tumour (DNT), whose natural evolution is much more benign than that of gliomas. The preoperative diagnosis of DNT, which is not yet feasible on the basis of available clinical and imaging data, would help optimise the therapeutic strate...
متن کاملEpilepsy surgery on dysembryoplastic neuroepithelial tumours.
Two rare cases of intractable epilepsy caused by Dysembryoplastic Neuroepithelial Tumours (DNET) are reported and their different management discussed. The first case required vagal nerve stimulation and radiosurgery while the later was operated with the help of neuronavigation. Both had good outcome according to Engel classification after a one year follow up.
متن کاملUsefulness of (11)C-Methionine PET in differential diagnosis of epileptogenic brain neoplasms.
Brain tumors are associated to more than 50% of patients with epilepsy, of which about 30% are drug-resistant. Epilepsy associated with brain tumors is multifactorial, but fundamentally depends on its location and histology. So, low-grade tumors are more epileptogenic than high-grade. In high-grade tumors and adult epilepsy is associated with increased frequency of neurological deficits. In low...
متن کاملDysembryoplastic Neuroepithelial Tumors.
Dysembryoplastic neuroepithelial tumor (DNT) is a benign glioneuronal neoplasm that most commonly occurs in children and young adults and may present with medically intractable, chronic seizures. Radiologically, this tumor is characterized by a cortical topography and lack of mass effect or perilesional edema. Partial complex seizures are the most common presentation. Three histologic subtypes ...
متن کاملEpileptogenic foci on subdural recording in intractable epilepsy patients with temporal dysembryoplastic neuroepithelial tumor.
To investigate the epileptogenic foci in dysembryoplastic neuroepithelial tumor (DNT) in the temporal lobe, we studied extraoperative electrocorticography (ECoG) with subdural electrode arrays from nine patients with intractable epilepsy due to temporal DNT. Ictal onset zones and irritative zones were decided by the ECoG. The locations of these zones were compared to the location of the tumor. ...
