Acute spontaneous subdural haematoma of arterial origin is very are. We report such a case who presented with sudden severe headache and vomiting rapidly becoming comatose. The patient was hypertensive but had no history of head trauma. and the source of bleeding was identified as a cortical artery ...
Although the localization of sacular aneurysm, which are the most frequent cause of subarachnoid haemorrhage, is determined exactly with cerebral angiography, the false negative angiography rate varies from 10 to 25 %. Thrombosis. vasospasm and a number of other factors have an effect on false negat...
A 59-year-old man presented with a one-year history of progressive dysphagia to the point that he could no longer swallow solid foods. Cervical spine X-Ray films demonstrated massive anterior new bone formation along the anterior surface of C3 to C7 vertebrae. Evaluation with barium swallow and cerv...

Migration of a peritoneal catheter of the shunt system into the scrotum was encountered in a seven-month-old who had received a V-P shunt. This was considered a rare complication of a V-P shunt and the causal mechanism of this kind of complication is discussed with a review of the literature.
Multiple spinal cord meningiomas are extremely rare and we describe a case in which there was an extradural meningioma in the cervical region and an intradural meningioma in the lumbar region. The tumor was pathologically identified as meningothelial meningioma in the cervical region but in the lumb...
A case with lumbosacral and cervical multiple root cysts that involved all roots except the thoracic region is presented and myelogram findings are discussed.
Medulloblastoma is a neuroectodermal tumor. It spreads particulary to the spinal cord. Supratentorial metastasis of medullablastoma is a rare form that generally occurs in subfrontal area and may be due to the low dosage of irradiation of this region.

Patients with anterior pathology in the atlanto-axial region who present as neurological emergencies require urgent brain-stem decompression. Anterior decompression remains the only alternative to progressive tetraplegia and a fatal outcome. In this study, the anatomical. embryological ad surgical p...
Brainstem auditory evoked potentials (BAEP) were obtained from 13 patients with pontocerebellar angle (PCA) tumors whose pathological diagnosis was as follows: 7 acoustic neurinoma, 3 meningioma, 1 neurinoma, 1 brainstem epidermoid tumor, 1 arteriovenous malformation. Notable abnormalities were obse...
The effects of Nicardipine. a Ca+ + channel blocker, on vasoconstriction of rabbit basilar artery in two different conditions, one with a dot contacting the wall of the artery and the other without, were investigated in this study. The Initial diameters of the basilar arteries were measured in all g...

In this study we investigated the influence of laser energy on the rheological properties of blood passing through the superior sagittal sinus. Twenty-two guinea-pigs were used. In the control group craniectomies were done and only the superior sagittal sinuses were exposed. This procedure had no si...

Despite advances in diagnosis and treatment, a brain abscess caused by anaerobic micro-organisms still poses a major clinical problem. An experimental model of anaerobic brain abscess in rat was developed to determine the effects of metronidazole and dexamethasone on the abscess thus formed. Rats we...
Six meningiomas with abundant hyaline inclusions (pseudopsammoma bodies) were studied in means of a panel of conventional histochemistry. In all six cases, the inclusions were PAS-positive, diastase resistant and stained picrophilic (yellow-bright orange) with van Gieson. Negative staining was obtai...
