Résumé
Endoscopy of pineal region tumours has been developed since the year 2000 either via a transventricular or extracerebral approach. The initial purpose of applying neuroendoscopy in the management of pineal region tumours was to resolve the obstructive hydrocephalus, and identify the pathological characteristics of the tumour. Based on this approach, a piecemeal resection of the tumour can be performed. The approaches, derived from the microsurgical pathway using an endoscope to expose the operative field, have been proposed either via an infratentorial supracerebellar approach or posterior transtentorial interhemispheric approach. Neuroendoscopic procedures can be considered as a therapeutic alternative to the microsurgical approach when CSF markers are negative. This procedure is considered mini-invasive for the approach along the surgical corridor access but extensive and in depth at the interface between the tumour and the surrounding neurological parenchyma. The limitations and complications are related to the type of procedure (mono- or bimanual) as well as the tumoral characteristics. Different approaches are presented in detail in order to avoid the occurrence of any surgical complications.
