OBJECT Pseudotumor cerebri, or benign intracranial hypertension, is a condition of raised intracranial pressure in the absence of a mass lesion or cerebral edema. It is characterized by headache and visual deterioration that may culminate in blindness. Pseudotumor cerebri is caused by venous sinus obstruction in an unknown percentage of cases. The purpose(More)
Rathke's cleft cyst (RCC) is a rare lesion of the pituitary gland that is often asymptomatic. The objective of this study was to further characterise the presenting symptoms, endocrinopathy and potential for recurrence of this lesion in an Australian population. The files of 12 patients with pathologically confirmed RCCs were reviewed retrospectively.(More)
Twelve patients in a series of 22 with giant intracranial aneurysms demonstrated neuroradiological features of partial or total spontaneous intra-aneurysmal thrombosis. The presence of this intra-aneurysmal clot significantly altered the computed tomographic appearance of the giant aneurysm. Massive intra-aneurysmal thrombosis did not protect against(More)
The present study examines ventricular volume before and after shunting in 16 infants with hydrocephalus and mixed aetiology and relates this parameter to rates of cerebrospinal fluid clearance, intracranial pressure and outcome. Following treatment all patients showed reduction in intracranial pressure and amelioration of the clinical manifestations of(More)
Evaluation of 192 cerebrospinal fluid shunts was performed using 1 mCi of technetium-99m DTPA which was injected into the shunt tubing. This was found to be a safe, simple method of evaluating shunt patency. No complications were noted with this procedure, nor was there any documented case of infection related to the injection of the isotope. The(More)
Thirty-six patients from a consecutive series of 41 patients with benign intracranial hypertension (BIH) were treated by cerebrospinal fluid shunting. In 12 patients this was selected as the primary treatment due to the severe deterioration of vision or concern regarding the possible adverse effects of steroids; all 12 patients showed rapid and complete(More)
Firstly, 14 patients are described who developed either an acquired Chiari malformation (ACM) alone (7 cases) or ACM and syringomyelia (7 cases) after lumbar subarachnoid space (SAS) shunting or in one case, epidural anaesthesia with SAS penetration. Four groups are considered: 3 cases with craniofacial dysostosis and communicating hydrocephalus (CH), 4(More)
The vein of Galen malformation is a midline arteriovenous fistula with aneurysmal dilatation of the vein of Galen. The clinical details of diagnosis and treatment in 13 patients with such lesions together with a review of 232 cases collected from the literature are presented in this report. There were 132 males, 77 females, and 36 cases in which the sex was(More)
We present a case of pseudotumour cerebri (PTC), which is important as it illustrates the effects of chronically raised CSF pressure, the relationship between PTC and venous sinus obstruction and the successful treatment of PTC using a venous sinus stent. A 38-year-old woman, previously diagnosed with PTC and unsuccessfully treated 10 years previously(More)
This paper is a retrospective review of all patients treated for a colloid cyst of the third ventricle at Royal Prince Alfred Hospital over an 18-year consecutive period. Our experience is fairly typical compared with other published series. Colloid cys ts made up 1.6% of tumours treated by the neurosurgical unit. Patients presented with non-specific(More)
