CTICasesPortopulmonary Shunt
Imaging findings
CT chest shows prominent para-esophageal varices, with a large venous channel directly communicating with the left inferior pulmonary vein, in a patient with a history of cryptogenic cirrhosis and subsequent liver transplant.
Key takeaways
A portopulmonary shunt (portal-to-pulmonary vein fistula) is a rare vascular connection that can develop in patients with severe portal hypertension. It allows portal venous blood to bypass the liver and right heart, draining directly into the left atrium, which can result in hypoxemia and systemic embolization.
