Dense Vessel Sign


Non contrast CT shows hyperdense and thickened right middle cerebral artery (MCA) (arrow) and corresponding normal MCA on the left (arrow head). CT Perfusion shows decreased Blood Flow in the right MCA territory consistent with acute infarct. CT Angiography confirms cutoff of the contrast flow in the proximal M2 segment. Last image shows clear infarct and normalization of the MCA size and density 8 days later.
