Desmoplastic infantile ganglioglioma and astrocytoma (DIG/DIA) are rare intracranial tumours of early childhood that involve superficial cerebral cortex and leptomeninges. Despite the large size of the tumour and the presence of poorly differentiated cells, it is believed that the prognosis of DIG/DIA is excellent. We report two patients with DIG/DIA who(More)
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)
Of 478 patients treated at a single institution for prostate cancer, 29 developed spinal cord or cauda equina compression. In 5 patients, spinal cord compression was the first evidence of malignancy. Clinical features were predominantly pain, weakness, sensory and sphincter disturbance. The median duration of symptoms was 2 weeks, although the diagnosis was(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)
A 27-year-old woman presented with a history of amenorrhea, visual disturbance, and diabetes insipidus. Magnetic resonance imaging showed a large enhancing suprasellar mass with associated edema involving the left striatum. The lesion was hypometabolic on fluorodeoxyglucose-positron emission tomography. At surgery, a subtotal resection of a vascular tumor(More)
PURPOSE To analyze prognostic factors, effects of treatment, and survival for patients with cerebral metastases from melanoma. PATIENTS AND METHODS All melanoma patients with cerebral metastases treated at the Sydney Melanoma Unit between 1952 and 2000 were identified. From 1985 to 2000, patients were diagnosed and treated using consistent modern(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)
The pathophysiology of PTS including idiopathic intracranial hypertension or 'BIH', remains controversial. The older literature frequently referred to pathology in the cerebral venous drainage but more modern imaging techniques (CT and early MR) failed to reveal gross venous pathology. The role of impaired cranial venous outflow has recently been(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)
Intracranial pressure changes occurring in patients with craniostenosis were studied by continuous monitoring of intracranial pressure in 20 children. Although clinical or radiologic evidence of intracranial hypertension was present in only one patient, 13 (65%) had persistent or episodic raised intracranial pressure. Intracranial hypertension occurred with(More)
