Perfusion MR imaging and proton MR spectroscopy in a case of dysembryroplastic neuroepithelial tumor

Dysembryoplastic neuroepithelial tumors (DNTs), which were first described by Daumas-Duport in 1988, are one of rare benign tumors usually associated with medically intractable seizures which date from childhood. 1 The clinical, pathologic and neuroradiologic findings of DNT have been described. 2 Recent advances in magnetic resonance imaging (MRI) technology allow the acquisition of cerebral microcirculation parameters by perfusion weighted imaging (PWI) and brain metabolic indices by MR spectroscopy (MRS). Several studies have shown the utility of PWI and MRS can improve the diagnostic accuracy of brain tumor, 3 we combine the two techniques to evaluate a case with DNT and suggest that wider application of these techniques is warranted.
