Observational Study
Pallidothalamic tractotomy (Forel's field H1-tomy) for dystonia: A preliminary results.
The pallidothalamic tract connects the globus pallidus internus with the ventroanterior and ventrolateral parts of the thalamus. Lesioning or stimulation of the pallidothalamic tract has ameliorating effects on dyskinesia and dystonia in patients with Parkinson disease. However, the effect of the procedure on dystonia due to other etiologies has not been reported. ⋯ This study suggests that pallidothalamic tractotomy can be an alternative treatment target for dystonia. A larger and longer prospective study is needed to elucidate the safety and efficacy of pallidothalamic tractotomy for dystonia.

Case Reports
Angiomatoid fibrous histiocytoma mimicking eosinophilic granuloma in a pediatric patient-A case report.
Angiomatoid fibrous histiocytoma (AFH) is a rare low-grade malignant tumor mainly occurring in soft tissues, and its incidence in the bones is extremely rare. Although most of the existing reports focus on the pathological features of AFH, only a few describe its imaging features. To our knowledge, this is the first case of AFH in the skull, and it is distinguished from eosinophilic granuloma based on imaging results. ⋯ To our knowledge, this is the first AFH that occured in the skull, and the main imaging manifestations of AFH are bone destruction with soft tissue mass. The characteristic features of AFH are its fibrillar component that showed low signal on T2-weighted imaging and septal or peripheral enhancement, and no dead bone in the mass.

Case Reports
A staged therapy for internal carotid artery dissection caused by vascular Eagle syndrome.
Eagle syndrome with stroke onset is a rare condition. Carotid stenting of dissected arteries and/or surgical resection of the elongated styloid process are frequently performed; however, there are no definitive criteria for selecting these treatments. ⋯ Stenting in the acute phase prevented the recurrence of stroke, and styloid process resection in the chronic phase cured vascular Eagle syndrome. This staged therapy could be beneficial in the treatment of vascular Eagle syndrome.

Dumbbell-shaped spinal schwannomas with intradural and extradural components are associated with higher complication rates. This may be in part due to epineurial dissection of the extradural component, which inevitably damages the functioning nerve fibers beneath the epineurium and may lead to dural defects that are often difficult to repair. ⋯ The radical intracapsular dissection technique described herein represents an alternative technique for the removal of dumbbell-shaped spinal schwannomas with intradural and extradural components.

Case Reports
Malignant Glioma developed on a patient under Deep Brain Stimulation patient: pitfalls in management. Case report.
Glioblastoma (GBM) is the most common aggressive malignant primary brain tumor, rarely concurrent in patients who require deep brain stimulation (DBS) implants. Despite the high incidence of these circumstances alone, the coexistence of both in a patient has been seldom reported. In this paper, we report a case of a patient suffering from a movement disorder treated with DBS who developed a GBM. ⋯ We advise the use of magnetic resonance imaging-safe devices; otherwise, we recommend keeping the system and proceeding with computed tomography imaging for diagnostic and management if necessary. The true relationship between chronic DBS stimulation and GBM is to be clarified.
