In this article two cases of primary malignant extrarenal rhabdoid tumour are described. In the affected children the brain and the spinal cord were the primary sites of origin of the tumour. The imaging findings are presented and the pathology discussed. Although the imaging features are non-specific, rhabdoid tumour should be included in the differential… (More)
Tentorial arteriovenous dural fistulae are uncommon. They are aggressive lesions: of all intracranial dural fistulae they are the most likely to present with haemorrhage. Treatment options include surgical excision or interruption of leptomeningeal draining veins and arterial embolisation in isolation or in combination with surgery. There has been one case… (More)
Three patients aged 48, 11 and 40 years, two of whom were recent recipients of renal transplants and one of a bone marrow transplant, developed seizures, with cortical blindness in two cases. All were immunosuppressed with cyclosporine and were hypertensive at the onset of symptoms. MRI showed predominantly posterior signal changes in all three cases. The… (More)
We reviewed the preoperative images of 28 patients with pathologically proven mesial temporal sclerosis, to assess thalamic asymmetry and signal change. A further 25 nonsurgical patients with temporal lobe epilepsy and unequivocal, unilateral changes of mesial temporal sclerosis, and 20 controls, were also reviewed. None of the control group had unequivocal… (More)
Congenital varicella syndrome is a rare disorder which follows maternal infection in the first or early second trimester. The syndrome comprises a number of malformations including microcephaly, cortical destruction and limb hypoplasia. We describe a case where there has been long-term survival following second trimester maternal infection. The clinical… (More)
Magnetic resonance imaging has been reported to have advantages over conventional angiography in the diagnosis of dural sinus thrombosis. A case report is presented describing the application of MR techniques including MR angiography, to diagnose and monitor therapy for dural sinus thrombosis.
Cerebellar hypoplasia may present with a wide variety of neurological and systemic features, ranging from aplasia causing neonatal death to mild hypoplasia in an asymptomatic adult. MRI clearly documents the size of the cerebellum and any associated abnormalities. We describe 7 cases of cerebellar hypoplasia of varying aetiology-3 inherited, 2 associated… (More)
The intrasphenoid form of basal cephalocele is uncommon. We describe the clinical, CT and MRI findings in two cases presenting in middle age with persistent cerebrospinal fluid rhinorrhoea. Emphasis is placed upon the imaging findings which aid in discrimination of intrasphenoidal cephalocele from more common causes of a sphenoid sinus mass.
Our purpose was to assess the value of routine administration of intravenous gadolinium-DTPA (Gd-DTPA) for cranial MR in a series of human immunodeficiency virus (HIV)-positive patients. Two radiologists retrospectively reviewed 150 consecutive examinations of 104 patients. All patients underwent unenhanced and contrast-enhanced images. Each radiologist… (More)
