T2W and FLAIR images show a round intraparenchymal lesion with
slightly hyperintense T2 signal and some surrounding vasogenic edema.
Pre-contrast T1W image demonstrates isointense T1 signal. Gradient
echo images demonstrate a rim of dark signal. Post-contrast images reveal
some peripheral enhancement.
DWI shows increased signal (restricted diffusion from intact RBCs within
clot). CT shows a corresponding hyperdense region. Angiography
demonstrates an AVM with an early draining vein.
