35 patients clinically diagnosed with transient ischemic attack (TIA) and 15 patients clinically diagnosed with reversible ischemic neurological deficits (RIND) were examined by computerized tomography (CT). 34% of TIA patients showed positive CT scans consisting of small hypodenase areas: 60% of RIND patients had larger lesions. In 20% of the overall group… (More)
Twelve patients with vascular malformations of the spinal cord have been treated by embolization at the Neuroradiological Department of the Ospedale Maggiore Niguarda Cà Granda from September 1981 to February 1984. Different materials and techniques have been used, including liophylised dura, Ivalon (PVA) and Isobutyl Cianoacrylate. All types of… (More)
The megadolichobasilar anomaly may be diagnosed by CT as an extra-axial lesion in the cerebellopontine angle. It enhances in a tubular fashion after intravenous injection of contrast. Hydrocephalus resulting from obstruction of CSF circulation may be demonstrated.
In this work, we examine the neuroradiologic features of the main non vascular clinical conditions responsible for secondary headache; excluding CSF hypotension, which will be treated extensively in another work in this supplement. Headache is not a constant feature of intracranial mass lesions, even of large extension. Headache has a high diagnostic value… (More)
Aneurysms of the vertebral artery (VA) are relatively uncommon, accounting for less than 0.5-3.0% of all aneurysms and 20% of aneurysms originating in the posterior fossa. There are three distinct forms of aneurysms: saccular, fusiform and dissecting. The diagnosis of dissecting aneurysm is based on the findings of angiography, surgery and autopsy.… (More)
145 children with acute lymphoblastic leukaemia (ALL) were evaluated over a period of 3 years in a multicentre study in which serial cranial computed tomographic (CT) scans of the brain were done. All patients were symptom-free. CT scans were graded as normal, borderline (slight or moderate cerebral atrophy), or pathological (severe cerebral atrophy). 62%… (More)
45 children with ALL treated with intrathecal Methotrexate and radiation therapy, all in hematologic remission, have been examined with brain CT at intervals varying from 3 to 6 years after completion of CNS prophylaxis. Abnormalities were detected in 20% of the children; the main findings were: calcifications within the brain parenchyma in 3 patients;… (More)
