Angiographic diagnosis of cerebral oedema.

Cerebral oedema is usually associated with brain vascular lesions, such as infarction, neoplasms, angiitis, thrombophlebitis, etc. and we consider that angiographic examination is essential for the diagnosis. In this paper we analyse the angiographic signs of cerebral oedema and the differential diagnosis between oedema and any associated lesions. We also consider that it is very important to establish a diagnosis between primary oedema and hydrocephalus with a view to establishing the correct treatment in each case.
