[Computed tomography in the diagnosis of cerebral cysticercosis]. / Computertomographie in der Diagnostik zerebraler Zystizerkose.

Cerebral cysticercosis was diagnosed in 16 patients by CT, both before and after contrast injection. In six patients the findings were confirmed at operation and histologically. In ten patients, the diagnosis was supported by typical findings on conventional radiographs of the thighs, calves and skull. The CT findings permitted classification of the patients into three types of disease.

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.

[Congenital cysts and teratomas in the sacrococcygeal region. Report of 2 cases]. / Kongenitale Zysten und Teratome in der Sakrokokzygealgegend. Darstellung von zwei Fällen.

Developmental abnormalities in the embryo may lead to tumours in the sacro-coccygeal area, so-called sacral cysts and the teratomas (5, 7). At birth they are caudal tumours of variable size covered with thin, stretched skin. Blood vessels can be seen through the skin, particularly in the mid-line. One gains the impression that the stretched skin could burst at any moment. It is assumed that these teratomas derive from the pluripotent cells of Hensen's node and then grow in front of the coccyx (2). They grow and spread in various directions, particularly in a dorsal and caudal direction extra-rectally and, to a lesser extent, into the pelvis in a pre-sacral position. The classification of these tumours depends on their spread. The spread and localisation of these tumours may cause stenosis of elongation of the rectum and displacement of small and large bowel and of the bladder.
