Intraoperative Fluorescence of Ganglogliomas and Neuroepithelial Dysembryoplastic Tumors

One of the key issues of tumour brain surgeries is to clearly define the borders of the tumor. The investigators proposed to evaluate the feasibility of intraoperative fluorescein guidance. Patients will be identified from the list of patients operated on under fluorescence to collect clinical datas. Surgical videos will be analyzed to assess the presence of intraoperative fluorescence and its subjectively judged intensity. MRI data will be extracted from the radiological reports to assess quality extraction. No additional data will be produced
