This group of authors came up with a scoring system to predict seizures in patients with brain AVMs. They retrospectively reviewed imaging studies of 1299 patients and found 33 with unruptured AVMs and seizures and 45 with unruptured lesions without seizures. Features that predicted seizures included: arterial dilation, pial recruitment, fistula, intranidal aneurysm, pial long draining vein, pseudophlebitic pattern, venous outflow obstruction, and venous ectasia. Because seizures are associated with significant morbidity, AVMs with these features may be targeted for treatment with surgery and/or embolization.
