An experimental saccular aneurysm model was made at the bifurcation of the common carotid artery in rats. Thirty albino rats were used. We histologically examined induced aneurysms in common carotid bifurcation of rats in the first, seventh and fourteenth day postoperatively and discussed the result...

Traumatic extradural haematomas (EDHs) comprise 1 to 3% of all head trauma admissions. The availability of computed tomography has increased the diagnosis of extradural haematomas. From January 1,1986 to December 31, 1994, 4,553 patients with head injury were admitted to the Department of Neurosurge...

A series of 41 patients with posttraumatic unilateral diffuse cerebral swelling was studied in order to assess clinical, radiological and operative findings, to determine the incidence and outcome, and to seek features that might identify patients at high risk of unilateral cerebral swelling and a p...

Eighteen patients with primary non-Hodgkin brain lymphomas without a history of any acquired or congenital immunodeficiency syndrome or organ trasplantation were reviewed retrospectively. Cases were selected from 2633 primary intracranial malignancies encountered between the years of 1987 and 1995. ...

Because of its long intracranial course, the abducens nerve can easily be injured due to the internal carotid artery aneurysm, Gradenigo's syndrome or surgical trauma. Therefore the intracranial course of this nerve is important. In this study, we used 42 dry skul1s, 8 fixed and 4 fresh cadavres. We...

Early detection of acute infarct has been more important since the introduction of new therapeutic regimens such as thrombolysis. In cerebrovascular accidents, first mode of investigation is computed tomography to rule out the possibility of hemorrhage; it is possible to diagnose acute infarction in...

Glioblastoma multiforme comprises 15-20 % of all intracranial tumours. It makes a peak between the fifth and seventh decades of life but it is rare in childhood. One of the radiological and clinical properhes of glioblastoma multiforme is perifocal vasogenic oedema associated with the tumour. In the...

Childhood meningiomas, besides their rarity, grow fast, recur frequently and have a dismal prognosis when compared with adult rumors. A five year old patient presenting with headache, emesis and left hemiparesia was admitted to our hospital in 1990. On computerized tomography a 85x80x87 mm mass in t...

Papillary-follicular thyroid carcinoma usually remains localized to the thyroid bed, and in cases of metastasis, almost always involves the lungs, bones, or liver. Brain metastasis is rare and there has been no reported case of epidural metastasis of thyroid carcinomas in the literature up to date. ...

This is the case report of an eight-year old boy with a benign osteoblastoma of the C3 vertebra. The clinical, radiological, gross and histopathological findings concerning the tumor are sufficiently characteristic and exclusive to justify the diagnosis of "osteoblastoma".

We report three examples of subependymoma presented as different clinicopathological aspects. One has an ependymomatous component, the second one is associated with craniopharyngioma. In third case, there is massive hemorrhage into the large subependymoma. The clinical and histopathological findings...
