The neuroradiologic observations on a case of growing giant intracranial aneurysm originating from a small saccular aneurysm are described in detail. The reports in the literature of growing giant aneurysms are reviewed. The computed tomographic and angiographic findings are described and special diagnostic difficulties analyzed. A correlation between the(More)
Thirty-two consecutive cases of nontraumatic intracerebellar hematomas detected by computed tomography are reviewed. A strong correlation was found between the clinical course and the volumetrically calculated size of the hematomas. Prompt evacuation has the best prognosis in cases that have an acute or subacute course (hematoma size, 22.5 to 66 cm3).(More)
Bilateral approximately symmetrical hypodense areas located in the thalamus were encountered in two patients who recovered clinically. Regression of the lesions could be observed on CT. The clinical symptoms corresponded to the thalamic location. Since these two patients recovered, no autopsy material is available to prove the nature of the causative(More)
Basilar artery occlusion was diagnosed by high-resolution computed tomography (CT) in 11 cases. The normal basilar artery imaged on plain CT scans has an attenuation value not higher than that of whole blood. If the CT attenuation value of the vessel is higher than that of blood, basilar artery occlusion is probably present. The tentative diagnosis can be(More)
A case of right-sided frontal intracerebral arteriovenous malformation fed mainly by both ethmoidal arteries is reported. The nidus was located intracerebrally, although its main feeders were dural arteries. It was drained partially through an intracerebral abnormal vein with aneurysmal dilatation of its proximal portion into the vein of Rosenthal and the(More)
Using an intravenous injection of 100-150 ml contrast medium (flow, 1-1.5 ml/sec) adjacent 2-mm-thick cuts are scanned at the level of the circle of Willis. After highlighting and multilevel image summation a complete picture of the vascular anatomy of the base of the brain is obtained. In this way aneurysms as small as 2-3 mm in diameter can be detected.(More)
