The risk of cerebral bleeding from arteriovenous malformations during pregnancy was examined and related to the different trimesters of pregnancy in these women. Some tentative guidelines are(More)
A patient presented with symptoms and signs of raised intracranial pressure and increasing focal deficit 13 months after stereotactic radiosurgical treatment of an arteriovenous malformation (AVM). Computed Tomography (CT) showed a mass lesion at the site of the previous abnormality typical of radiation necrosis, but with features identical to those of a(More)
