title: Pseudopathologic brain parenchymal enhancement due to venous reflux from left-sided injection and brachiocephalic vein narrowing.
abstract: In this report, we present a case of a patient with CT angiographic artifacts related to left-sided venous injection resulting in a striking pattern of enhancement simulating vascular abnormalities, which prompted additional diagnostic imaging. To our knowledge, no similar case has been reported in the published literature to date.
