Only when we saw them building roads, forts, killing off the game, committing buffalo genocide, when we saw them ripping off our land for gold, only then did we realize that what they wanted was our land. They took away ou...

Objective: Recent studies of iron mechanism in the brain have indicated that there may be a relationship between transferrin receptor (TfR) expression and histological malignancy._ TfR expression may also reflect cell proliferation. We investigated TfR staining intensity in intracranial meningiomas,...

Objective: The effects of lifarizine (RS-87476) and nimodipine on lactate concentrations in ischemic forebrain were evaluated in a rat model of bilateral carotid artery ligation. Methods: Eighteen rats were randomly assigned to three groups (control, lifarizine treatment, and nimodipine treatment)....

Objective: Choroid plexus neoplasms originate from choroid plexus epithelium. They are classified as papillomas and carcinomas histopathologically. The aim of this study is to discuss the signs, symptoms, treatment modalities and surgical results of this entities. Method: Ten cases of choroid plexu...

Objective: Computer-assisted stereotactic frameless navigation techniques are used in many centers for intracranial neurosurgical procedures. In this study, we assessed the accuracy and the clinical usefulness of a frameless system based on the optical digitizer in a variety of intracranial procedur...

Objective: The neuroprotective effects of ebselen were investigated in a rat spinal cord trauma model. Methods:Thirty-six Wistar albino rats were studied in four groups of nine animals each: sham-operated controls; trauma-only controls; and two ebselen treatment groups (administered 1 hour after inj...

Objective: Predicting the age of subdural hematomas on computed tomography (CT) scans is particularly significant for forensic reasons, and for understanding the lesion's natural history, pathogenesis, and morphology. A case of mixed-density subdural hematoma on CT is discussed, and the classificati...

Intramedullary lipomas are slow-growing congenital tumors that are usually not amenable to complete resection. In this article, we present a rare case of cervical intramedullary lipoma not associated with spinal dysraphism.

A 28-year-old man sustained blunt forehead trauma in a traffic accident. He had a right orbital roof fracture and there was loss of vision in the right eye. At presentation, the visual acuity in the injured eye was light perception without projection, and there was a right afferent pupillary defect....

Objective: The cervical synovial cysts are unusual extradural lesions which may cause radiculopathy or spinal cord compression. The aim of this paper is to describe a case of cervical synovial cyst and discusses the clinical, radiological, and pathological features of these rare lesions. Methods: A...

A 26-year-old male with a type II sylvian arachnoid cyst of the middle cranial fossa developed spontaneous subdural hemorrhage. The only presenting sign was headache. The hematoma was evacuated and during surgery it was noted that the cyst was communicating with the subarachnoid and subdural spaces....
