CTICasesIatrogenic hydrothorax
Imaging findings
Chest radiograph shows a central venous catheter coursing abnormally over the left clavicle and extending straight down along the aortic arch. CT confirms the catheter is located within the left pleural space, resulting in a large iatrogenic hydrothorax.
Key takeaways
Misplaced central venous catheters can enter the pleural space instead of the venous system. Radiographic signs include an atypical course, and injection of fluids through a misplaced CVC leads to a rapid, large iatrogenic pleural effusion.
