[Neurosurgeon-neuropathologist collaboration in cerebral tumors diagnosis]

The aim of the neurosurgical treatment in neuro-oncology is multiple: diagnostic (obtaining of a precise histopathological diagnosis to improve the treatment and the further prognosis), symptomatic (the improvement of the neurological clinical features by decreasing intracranial pressure) and therapeutic (to obtain a cytoreductive treatment, by complete or partial exeresis of the tumoural mass). To establish a precise histopathological diagnosis, during the intervention and latter, on the paraffin sections, the neuropathologist must examine the neurosurgical drawings knowing the history of the illness, the clinical and radiological aspects of the case in study, which complains a good cooperation between neurosurgeon and neuropathologist. To initiate the procedures of histopathological processing of various neurosurgical drawings, the neuropathologist must understand very well the surgical procedure. This is the reason of this study: to present different neurosurgical technics; the choose of one of these essentially depends on the location and size of the cerebral tumour, on neuroradiological characteristics and presumptive histopathological diagnosis and on the neurological status, the age and the general condition of the patient.
