Clinical-tomographic evolution of a giant intracranial aneurysm. Case report.

The Authors report about the case of one patient with stroke picture of aphasia and right pyramidal deficiency hemisyndrome evidencing at the CT a picture of multiple bilateral malacic areas associated with a picture of bilateral megadolichosiphon. The later tomographic controls evidenced the occurrence of a right latero-supra-sellar expansive injury compatible with a picture of giant aneurysm of the homolateral carotidal siphon. The Authors analyze the clinical, neuroradiological and anatomopathologic findings in the light of the present publications in the recent literature.

[Comparison of high-resolution arterial echography and angiography in the diagnosis of atheromatous lesions of the external carotid]. / Confronto tra ecografia arteriosa ad alta risoluzione ed angiografia nella diagnosi delle lesioni ateromasiche della carotide extracranica.

Personal experience about a correlative study on ultrasonographic and angiographic methods executed on carotid artery is reported. Usual techniques are described and result discordances are considered. Stenosis level is subdivided in four different types: normal, less than 45, 45-75%, greater than 75%. Authors examine in which stenosis range one technique can be superimposed on the other one and show limits and possibilities. Moreover complementary and interdependence position of these two techniques are stressed with respect to atherosclerotic disease study.

Cerebral arterial spasm after subarachnoid hemorrhage. A case report with SPECT and iodine-123 HIPDM.

Cerebral arterial spasm following subarachnoid hemorrhage can be responsible for secondary neurological deficits and can influence history, prognosis, and results of surgical treatment. The demonstration of vasospasm can be important for therapy. The use of I-123 HIPDM and SPECT in evaluating regional cerebral blood flow showed the effects on cerebral perfusion of diffuse arterial spasm in a case of subarachnoid hemorrhage and its recovery. There was a parallel with clinical neurological status.
