Epilepsy Associated Tumors And Tumor-Like Lesions

  • Horst Urbach
Part of the Medical Radiology book series (MEDRAD)


Glioneuronal rather than glial tumors are found in around 20% of patients with drug-resistant focal epilepsies. Gangliogliomas, dysembryoplastic neuroepithelial tumours (DNTs), angiocentric gliomas, pilocytic astrocytomas, and pleomorphic xanthoastrocytomas (PXAs) show characteristic imaging profiles clearly different from diffusely infiltrating gliomas. Epidermoids and dermoids are considered tumor like lesions with likewise specific imaging findings.
