简要总结
Differential diagnoses of MVNT include DNT (dysembryoplastic neuroepithelial tumor), low-grade gliomas, cortical dysplasias or even hamartomas.
详细描述
Differential diagnoses of MVNT include DNT (dysembryoplastic neuroepithelial tumor), low-grade gliomas, cortical dysplasias or even hamartomas.
However, in order to avoid an invasive surgical procedure to remove the lesion, a certain diagnosis of its benignity is essential. The contribution of advanced techniques in MRI, such as spectroscopy in the characterization of these lesions, has not yet been studied today
