Secondary Parkinsonism in a Patient With a Cerebral Cavernous Hemangioma Treated With Stereotactic Radiosurgery.

Secondary parkinsonism is defined with some symptoms similar to idiopathic Parkinson's disease, but with different etiologies. And cerebral cavernous hemangioma is one of the rare cases. A 51-year-old, male patient was consulted with tremor, rigidity and bradykinesia on the right upper extremity.

Primary Ewing Sarcoma of Frontotemporal Bone in Geriatric Patient.

Background: Ewing sarcoma is a rare primary malignant bone tumor, which mainly affects children and adolescents. Calvarial bone involvement and its appearance in elderly patients are extremely rare.

Case Description: We presented a 68-year-old female patient with headache and right frontotemporal swelling.

Intracerebral Hemorrhage with Multiple Intracranial Arterial Stenoses in a Synthetic Cannabinoid "Spice" User.

Synthetic cannabinoids (spice), which are used frequently worldwide, are more potent than herbal compounds and also have more side effects in comparison. A 23-year-old male was admitted to the emergency unit with altered consciousness. There was no sign of trauma, and his medical history did not reveal any chronic illness.

Serum endocan levels before and after surgery on low-grade gliomas.

Background: Endocan has been shown to be a marker for several cancers and may show degree of malignancy. The aim of this study is to assess serum levels of endocan before and after surgery on low-grade gliomas (LGGs).

Methods: Endocan was assayed by commercially available enzyme-linked immunosorbent assay (ELISA) kits in a total of 19 patients and 12 controls.

Surgical and anesthesiological considerations of awake craniotomy: Cerrahpasa experience.

Aim: Awake craniotomy (AC) with electrical cortical stimulation has become popular during the last ten years although the basic principles were introduced almost 50 years ago. The aim of this paper is to share with the readers our experience in 25 patients who underwent AC with electrical stimulation.

Material And Methods: Twenty-five patients who underwent AC between 2010 and 2013 are the subjects of this paper.

Low-grade temporal gliomas: surgical strategy and long-term seizure outcome.

Low-grade gliomas (LGGs) are generally located in temporal lobe and cause medically-intractable seizure so that surgical treatment becomes inevitable. This study includes a retrospective analysis of our patients with temporal LGGs retrieved from our epilepsy surgery data base and tries to present appropriate surgical approach and long-term seizure and anti-epileptic drug (AED) outcomes. Fifty-three patients including children and adults underwent surgery on temporal lobe LGGs and 35 patients were reached to report seizure and AED outcomes.

Direct venous spinal reabsorption of cerebrospinal fluid: a new concept with serial magnetic resonance cisternography in rabbits.

Object: For nearly 100 years it has been believed that the main reabsorption of CSF occurs in arachnoid projections into the superior sagittal sinus, but a significant number of experiments and cases conflict with this hypothesis. According to recently published studies, CSF is permanently produced and absorbed in the whole CSF system. Clusters of arachnoidal villi, which are speculated to have a role in the reabsorption of CSF, have recently been revealed in the dorsal root of the spinal nerves.

Pneumatization degree of the anterior clinoid process: a new classification.

The objective of this study is to determine the incidence and degree of anterior clinoid process pneumatization, in addition highlighting to their clinical significance. Multidetector-row CT scans of the skull base were reviewed in 648 subjects between 2007 and 2008. The presence of pneumatized anterior clinoid process and its degree were studied and documented.

Reconstruction of growing skull fracture with in situ galeal graft duraplasty and porous polyethylene sheet.

Objective: In growing skull fractures with large calvarial defects, it is difficult to use autografts for reconstruction and it requires alternative materials for cranioplasty. In this report, the authors describe their experience and introduce reconstruction of the growing skull fractures' defects with a porous polyethylene sheet (Medpor) and with a novel technique of duraplasty with in situ galeal graft, which avoid the potentially risky dissection and exposure of brain tissue. The goal of this study was to clarify effective surgical methods and to provide the rationale for these techniques.
