Imaging findings
CT shows a vertically running vessel lateral to the aortic arch, identified as a remnant left SVC or vein of Marshall, which appears to drain into the coronary sinus. The coronary sinus may appear small.
Key takeaways
The Vein of Marshall (remnant of the left SVC) is a normal anatomical variant that can be seen as a vertically running vessel lateral to the aortic arch. It typically drains into the coronary sinus. In some cases, if the coronary sinus ostium is atretic, blood may drain into the SVC via anastomoses.
