[Radiology of cerebrovascular malformations].

Cerebral vascular malformations are, after hypertension, the second most frequent cause of non-traumatic, intracerebral hemorrhage. A reliable intravital diagnosis only became possible with radiological diagnostic methods which also contributed significantly to the development of therapeutic concepts. Diagnostic and therapeutic possibilities for the various forms of cerebral vascular malformations are surveyed in the present review. Since radiology occupies a central position in the diagnosis and (in the meantime also) therapy of cerebral vascular malformations, epidemiological and prognostic factors are also discussed in detail.
