[Cyberknife and benign pathologies].

Conventional radiotherapy is known to be an effective treatment approach even for "benign" pathologies. However, this kind of treatment yields a high potential for side effects. The Cyberknife, a robotic stereotactic radiotherapy device, enables to offset a large proportion of the disadvantages encountered with conventional radiotherapy essentially through the high precision of dose administration and sparing of healthy tissues. Therefore, it seems to be a treatment of choice in the approach of some benign intracranial diseases. We review published data on indications and outcome of Cyberknife for intracranial "non-malignant" disease.
