Imaging findings
A portable chest radiograph and subsequent chest CT demonstrate a shunt catheter originating from the abdomen, passing subcutaneously over the anterior chest wall, and entering the pleural space to drain refractory ascites.
Key takeaways
Peritoneopleural shunts are occasionally used to manage refractory ascites by routing peritoneal fluid directly into the pleural cavity. Recognizing the expected course and appearance of these specialized drainage systems on portable chest radiographs prevents the misinterpretation of catheter malposition or pleural fluid as a new acute complication.
