Perfusion sensitive contrast-enhanced magnetic resonance imaging of dysembryoplastic neuroepithelial tumour: a new neuroimaging finding

Dysembryoplastic neuroepithelial tumours (DNTs) are benign lesions affecting young people and are associated with epilepsy. There have been described more than 300 cases in the literature and the clinical, pathological and radiological findings are well known. Recent advances in neuroimaging allow the acquisition of cerebral microcirculation parameters by perfusion weighted imaging, giving additional diagnostic information improving the diagnostic accuracy. The aim of this study is to show the perfusion sensitive contrast-enhanced magnetic resonance imaging findings of a case of DNT as an additional neuroradiological finding. Further investigation of microcirculation parameters may be helpful to establish the correct diagnosis of such tumours. 46 2 184 188
