A case of cavernous angioma in the right temporoparieto-occipital area is reported. The unusually large area of calcification and cystic formation presented problems in preoperative diagnosis. The tumor was treated successfully by subtotal excision.
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)
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)
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)
Computed tomography (CT) of 22 patients with histologically verified oligodendroglioma showed calcifications in 20 cases and contrast enhancement in 14. All of the enhancing cases proved to have malignant histological features. In 2 of the 14 malignant tumors, definite CT evidence (fluid-fluid level) of a cystic component was present.
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)
After studying the histograms of 87 supratentorial brain tumors and 4 abscesses before and after contrast medium injection and analyzing the results, we attempt to determine characteristic signs of the various kinds of tumors in order to improve their pathologic definition. The meningiomas, astrocytomas, and abscesses seem to show the most standard signs.… (More)
Two cases of subdural hematoma associated with dural metastasis are reported. The computed tomographic and angiographic features are presented. The possible pathogenetic mechanism is discussed. Our cases support the idea of obstruction of dural capillaries by neoplastic cells and subsequent subdural bleeding.
