Vestibular Shwannomas are responsible for 80-90% of the cerebelar-pontine angle tumors and their incidence is of 0.8 to 20.5% of all tumors. Unilateral and progressive hearing loss is the most frequent and premature symptom, and tinnitus is the second most common complaint. Only 5% of the patients have normal audiograms. In this case the patient complained of ipsilateral facial numbness and wea...

Ritscher-Schinzel syndrome was first described 1987, in the case of two sisters of healthy parents who have had posterior fossa malformations, congenital heart defects and craniofacial anomalies (5). It is believed that this is an autosomal recessive hereditary disorder. So far, according to ORD data (Office of Rare Disease of the National Institutes of Health), only about 30 cases are reported...

In spite of major recent advances in diffuse intrinsic pontine glioma (DIPG) molecular characterization, this body of knowledge has not yet translated into better treatments. To date, more than 250 clinical trials evaluating radiotherapy along with conventional cytotoxic chemotherapy as well as newer biologic agents have failed to improve the dismal outcome when compared to palliative radiation...

An open-label phase II study (ACNS0126) testing the efficacy of chemoradiotherapy with temozolomide (TMZ) followed by adjuvant TMZ was conducted by the Children's Oncology Group. During the period from July 6, 2004 through September 6, 2005, 63 children with newly diagnosed diffuse intrinsic pontine glioma (DIPG) were enrolled in the study. All patients received TMZ at a dosage of 90 mg/m(2)/da...

Introduction: Vertebrobasilar dolichoectasia (VBD) is an arterial disease characterized by dilatation, elongation, and tortuosity of the vertebral basilar arteries. VBD can generate intracranial hemorrhage, compression brainstem, ischemic stroke as most common presentation. Millard-Gubler syndrome (MGS) a pontine-crossed affecting pons at level facial nerve nucleus. We present unusual case post...

Several targets and targeting methods are utilized in stereotactic surgery to achieve tremor suppression for patients with intractable tremor. Recent developments in magnetic resonance imaging, including diffusion tensor imaging, have enabled the setting of appropriate targets in stereotactic surgery. In this retrospective study, the optimal target to suppress tremors in stereotactic surgery wa...

Two adult patients with brainstem glioma were successfully treated surgically. A 37-year-old male had a dorsally exophytic pontine glioma developing from the fourth ventricular fundus, and another 27year-old male an intrinsic nodular mesencephalic glioma. Preoperative magnetic resonance imaging clearly visualized the tumor margin in both cases, and showed the relationship between the tumor and ...

This open-access collection of 11 selected articles covers a small but quite diverse and interesting part of the much wider range of scientific topics presented at the 16th International Conference on Small-Angle Scattering (SAS2015) in Berlin. The topics contained here describe the particular directions in which small-angle scattering is developing at the current moment and which will become i...

Four cases of schwannoma originating from the lower cranial nerves are presented. Case 1 is a schwannoma of the vagus nerve in the parapharyngeal space. The operation was performed by the transcervical approach. Although the tumor capsule was not dissected from the vagus nerve, hoarseness and dysphagia happened transiently after the operation. Case 2 is a schwannoma in the jugular foramen. The ...
