title: Angiography before and after radiotherapy for a thalamic tumor.
abstract: A patient with a thalamic tumor received radiotherapy. A right cerebral angiogram seven days after the irradiation was finished revealed increased vascularity, early filled deep cerebral veins and signs of increased mass. A subsequent angiogram showed gradual regression of these features. There is no literature on angiographic progression with early venous filling following radiotherapy.
