Possibilities and limits of computed tomography and angiography in diagnosis of cerebral vascular malformations.
CT findings in 18 patients with cerebral vascular malformations are presented. The following findings were established: 9 angiomas, 4 spontaneous intracerebral haematomas after angioma rupture, 3 aneurysms, 1 aneurysm of vena magna Galeni and 1 megasinus. Contrast medium was administered during every CT screening. All the CT results were controlled by angiography and 10 patients were surgically treated. The authors point out the limits in possibilities of CT to diagnose cerebral vascular malformations. They also discuss the possible errors during CT procedure and deal with the problems of diagnostic differentiation of results. Discussing some cases of cerebral vascular malformations, the authors are trying to evaluate the reliability of the CT diagnostic method had compare it with angiography.
