Edema in cerebrovascular disease.

To date a few clinical methods give a certain hint as to the presence of brain edema and even its most probable localization; only one method, the recently developed computer tomography can be regarded as fairly reliable. However, as long as the pathogenesis of brain edema is not yet sufficiently elucidated and therapeutic methods are not developed either to prevent or remove intra-or extra-cellular edema distinctly and separately in experimental lesions, the lack of adequate technology for a refined diagnosis in the human is not urgent.
