Esophageal varices. In a 38-year-old male with liver cirrhosis, the axial contrast-enhanced CT scan (a) on the portal vein phase demonstrated that esophageal varices (red arrow) were enhanced channels adjacent to the surface of the esophageal lumen, with round, tubular, or scalloped borders. Upper gastrointestinal endoscopy (b) showed several tortuous varices in the esophagus.
