[Discographic demonstration of a posttraumatic transvertebral lumbar disc herniation (author's transl)].

The differential-diagnostic and methodological difficulties in demonstrating rare traumatic lesions of the lumbar intervertebral discs are described, in which transvertebral herniation of the nucleus pulposus through the compressed vertebral body along the fracture lines take place. The diagnosis could only be established by transdural lumbar discography. The neuroradiological findings and the validity of lumbar discography in comparison to the other investigations of the lumbar spine with help of contrast material are discussed.

[Results of radiation therapy in 214 primary cerebral tumors and 27 metastases to the brain (1969--1978) (author's transl)].

The results of radiation therapy in 241 patients with a cerebral tumor are reported. A total of 214 primary cerebral tumors and of 27 metastases to the brain was irradiated at the medical radiation institute of the University of Tübingen within the period from 1969 to 1978. Of the cases, 56% underwent primary radiation therapy, and 44% postoperative treatment. Histologically verified diagnoses are existing for 68.5% of all the cases. The average survival rate (months) for the different tumor groups--according to the classification of Zülch--is compared with data in literature. The problems concerning the indication of radiation therapy are discussed. The results underline the merely palliative character of actual radiation therapy in the treatment of most cerebral tumors. Its value is to be found in the prevention resp. retardation of recurrences. Irradiation, even palliative irradiation, or cerebral metastases may be recommended without restriction, as special importance has to be attached to the aspect of an improvement of life quality.

[The angiographic demonstration of infra-tentorial tumors with identical manifestations, localisation and histology in identical twins (author's transl)].

The angiographic diagnostic features of concordant tumors of the posterior fossa in monozygotic twins are described. In both cotwins cranio-spinal subependymomas were found which had grown through the foramen magnum and reached from the fourth ventricle down to the second cervical vertebra. Thereby, the conformity of the clinical mainifestation, symptomotology and the course of the disease, the localisation and extent of the tumors as well as the neuroradiologic findings and the histologic features of the tumors were particularly striking. After a review and critical summary of the few cases of concordant affections with brain tumors in identical twins published in the literature at present our couple is discussed under the question of the possible influence of genetic factors or a hereditary disposition on the development of cerebral tumors.
