Although there is an ongoing debate about the ideal management of vestibular schwannomas, radiosurgical treatment has become popular in the past decade with good to excellent results reported. Given the young age at presentation, the bilateral nature of vestibular schwanomas, the presence of other associated central nervous system tumors, patients with neurofibromatosis Type 2 (NF2) are very complex and present significant management challenges. Although results do not seem to be as good as for patients with sporadic unilateral tumors, stereotactic radiosurgery has proven a safe, attractive, and effective management modality for NF2 vestibular schwannomas...

Malignnant Schwannom is an aggressive tissue tumor that is more cnmitutnh found m assoiiatiun with Ion Recklinghausens disease. The solitary tumors although rarer have a better prognosis when compared to those associated witk tan Recklinghausens disease. Parupharyngeui tumors are rare and a majority af these are benign salivary or neurogenie tumors, A malignant Schwannoma at this site is very infrequent with only four earn reported so far. The tase of a 16 year old girl with a parapharynccal malignant Schwnnaomu is presented Jor its rarity and our experience in dealing with it...

Schwanomas originating from the brachial plexus, although rare, may be mistaken for another type of tumour. A 40 year-old woman, who had been treated years earlier for a breast adenocarcinoma, showed in the 5-year follow-up magnetic resonance examination a localized lesion in the right brachial plexus. The presumptive radiological diagnosis was a metastasis from the primary adenocarcinoma. Following surgical access via the right axilla, a well-circumscribed mass in the brachial plexus was detected. Under intraoperative electrophysiological guidance, the lesion was observed to depend on the ulnar nerve and its complete resection was possible without compromising nerve function...

Stereotactic radiotherapy delivers allows for a highly precise irradiation, and was originally developed in the 70s by neurosurgeons. Gradually, it has been developed in extracranial indications. Moreover new innovative treatment devices such as the robotic radiosurgery with CyberKnife have emerged. Indications are currently being validated by the HAS in intracranial locations that are treated by conventional radiosurgery for several decades. Three robotic radiosurgery facilities were opened in France in 2006 thanks to a grant from the INCa...

Since the first pioneering work in the area of tumors of the spine, medical professionals have sought to determine the proper role of spine surgery in the management of spinal tumors. Experience has proven that spine surgery is effective in the treatment of spinal cord compression for decreasing pain and improving quality of life with low rates of surgical complications. We use several staging systems to assess the patient's prognosis, to determine the best type of tumoral resection in preoperative surgical planning, and to provide guidance as to the best therapeutic option for the patient...
