Intracerebral schwannoma: case report and review.

A case of intraparenchymal schwannoma of the brain in a 4-year-old girl is presented. Most of the small number of intracranial schwannomas unassociated with cranial nerves, reported have occurred in children or young adults. There is no male or female predominance. Most of the parenchymatous schwannomas are located supratentorially. The presence of a cyst together with the tumor appears to be characteristic of intraparenchymal schwannoma of the brain.

Cerebral salt wasting syndrome.

Hyponatremia following acute or chronic central nervous system injury which is due to excessive Na+ loss in the urine without an increase in the body fluid, has been described as Cerebral Salt Wasting Syndrome (CSWS). This syndrome is often confused with dilutional hyponatremia secondary to inappropriate ADH secretion. Accurate diagnosis and management are mandatory for to improve the course of the disease. In this study a patient with CSW Syndrome is presented and the treatment and diagnosis of this syndrome are discussed in view of the literature.

Symptomatology, evaluation and treatment of aquaductal stenosis.

Thirty-three surgical treated cases of aquaductal stenosis are presented. Beside the classical clinical representation of the disease, the symptomatology caused by anterior and posterior herniation of dilated third ventricle is discussed. The impotence in one male patient which is caused by anterior herniation was proved by means of NPT (Nocturnal Penile Tumescence) recording. In one patient bilateral partial deafness and Parinaud syndrome which was caused by posterior herniation was cured by third ventriculostomy. In the surgical treatment of aquaductal stenosis, the effectiveness of various surgical procedures are presented and the superiority of third ventriculostomy by microtechnique is emphasised.

A giant meningioma of the fourth ventricle associated with Sturge-Weber disease.

A case of meningioma without dural attachment within the fourth ventricle associated with Sturge-Weber disease is reported. Review of the literature revealed that meningiomas arising from the choroid plexus of the fourth ventricle and lying totally within the fourth ventricle are very rare. Coexistence of Sturge-Weber disease with meningioma of the fourth ventricle has never been reported, as far as we could find out.

Brain tumour associated with intracranial arterial aneurysm.

Four cases of brain tumour associated with intracranial aneurysm are presented, and the available literature is reviewed. The association of brain tumours and arterial aneurysms is not well documented in neurosurgical literature. Reports of the association of giant aneurysms with brain tumours are rare. We could find only five such cases, and one of our cases is the sixth. The operative mortality of the patient with coexisting brain tumour and cerebral aneurysm is high. Two of our cases died postoperatively, one from pre-existing cardiac disease, and the other from hypothalamic vascular insuffiency related to surgery.

Surgical treatment of traumatic carotid cavernous fistulas.

Six cases of traumatic corotid cavernous fistulae treated by a combination of trapping and embolization are reported. The advantages and disadvantages of various operative procedures in the treatment of carotid cavernous fistulas are discussed. In our opinion a combination of trapping and embolization has advantages over other methods in the treatment of traumatic carotid cavernous fistulae.

Aneurysm and arteriovenous malformation of the spinal cord.

A case is presented in which microsurgical technique was used to excise an intramedullary vascular lesion of the spinal cord. This kind of vascular pathology is uncommon. In this case, a radical excision of the malformation was obtained using the microscope. What appeared to an associated intramedullary aneurysm was totally removed.

Intracranial tuberculomas.

In this paper the clinical findings, operation results and histological diagnosis of eight patients with intracranial tuberculomas are described, which were admitted to the Neurosurgical Clinic of Ankara University, Faculty of Medicine, during the years 1967-1975, among the 1,015 histologically verified intracranial tumours. Our impression by reviewing previous papers on this matter is, that although tuberculomas are not so frequently seen as before, they still count as a certain percentage in Turkey.
