Background Sinus histiocytosis (Rosai–Dorfman disease) with massive lymphadenopathy is a rare nonneoplastic and nonlangerhans cell proliferation disorder of the histiocytes. Extranodal location with or without lymphadenopathy occurs in about 40 % of the cases. Intracranial location is rare in children often mimicking meningiomas. The parasphenoidal region is more frequently involved though intraxial...
Glioblastoma multiforme (GBM), a highly malignant primary brain tumor, is difficult to distinguish from from its surrounding functioning tissue under direct vision in the operating field, since it grows in an infiltrative growth pattern. The main challenge in the surgical treatment of GBM is to fully resect the tumor and avoid neurological impairment. In this paper we extend previous proof-of-principle...
Deep brain stimulation (DBS) is a surgical treatment involving the implantation of a medical device called a brain pacemaker, which sends electrical impulses to specific regions of the brain for treatment of movement disorders. Because of the small size of the surgical target and possible shift of the deep brain structures due to air invasion when the dura is opened, intra-operative adjustment of...
It is generally accepted that the completeness of resection in malignant gliomas should be as complete as possible. Maximal cytoreductive surgery is generally performed aiming at removing at least that part of the tumor that accumulates a contrast agent for magnetic resonance imaging (contrast-enhanced MRI) (1;2). Complete resection of contrast enhancing tumor regions as judged by post-operative MRI...
Deep brain stimulation (DBS) is a surgical treatment for movement disorders like Parkison's disease or essential tremor. Although DBS is effective in the treatment, the mechanism of action is not clearly understood by now. The accessibility to deep brain regions through the DBS implanted electrodes can give the opportunity to monitor the local activity of nuclei once accessible only during surgical...
Deep brain stimulation (DBS) is considered a surgical treatment alternative for Parkinson disease (PD) patients with intractable tremor or for those patients who are affected by long-term complications of levodopa therapy such as motor fluctuations and severe dyskinesias. However, the susceptible accuracy of placement of the DBS electrode inside the brain nucleus determines the therapeutic efficacy...
