Summary

Two cases of giant intracerebral aneurysm are presented. Both exhibit increased absorption values in a circumferential configuration peripherally after the administration of contrast material. In addition, one case demonstrates a coexistent contralateral chronic subdural hematoma. No previous example of intracranial aneurysm exhibiting this configuration on computed tomography has been described in the literature. The operative, computed tomographic, radionuclide and angiographic findings are described and the differential diagnosis discussed.

Zusammenfassung

Es werden zwei Fälle von intrazerebralem Riesenaneurysma geschildert. Beide zeigten eine ringförmige dichte Zunahme in der Peripherie nach Gabe von Kontrastmittel. Außerdem zeigte ein Fall ein begleitendes chronisches Subduralhämatom auf der Gegenseite. Kein Fall von intrakraniellem Aneurysma mit diesen Charakteristika in der computerisierten axialen Schädeltomographie ist bisher in der Literatur beschrieben worden. Es werden der operative Befund und das Ergebnis des CAT, der Hirnszintigraphie und der Angiographie geschildert und die Differentialdiagnose diskutiert.
