Abstract
Several papers have already described the computed tomographic (CT) findings in arteriovenous malformations (AVMs) of the brain. In a pop-ulation of larger and unruptured AVMs, however, improved resolution CT has made it possible to demonstrate findings not previously appreciated: (a) major and minor mass effects in the absence of rupture of an AVM (33 of 60 cases); (b) cisternal enlargement secondary to vessel ectasia and tortuosity; (c) extensive edema of white matter; (d) the detailed features of finer and coarser calcifications of the malformation; (e) gray matter changes, disturbances in the gray-white matter interface, and intrinsic hypodense regions within the AVM; and (f) visualization of small vessels on intravenous enhancement.
