Which imaging finding is typical of a pleuroperitoneal leak in PD?

• A. Normal chest X-ray.
• B. Lung nodules.
• C. New pleural effusion on imaging.
• D. Cardiomegaly.

Answer: (C)

The main idea here is that a pleuroperitoneal leak lets dialysate enter the pleural space, so imaging will show an abnormal accumulation of fluid in the chest. In a patient on peritoneal dialysis, this leak typically presents as a new, unilateral pleural effusion—often on the right side—visible on chest X-ray or other imaging. That new effusion reflects the dialysate that has crossed into the pleural cavity. Why this is the best answer: the appearance of a fresh pleural effusion directly indicates fluid collecting where it shouldn’t be, which matches the pathophysiology of a pleuroperitoneal leak. Other imaging findings don’t align with this process: a normal chest X-ray would miss the complication, lung nodules aren’t related to a dialysate leak, and cardiomegaly points to heart-related issues rather than a PD-associated translocation of fluid. If needed, pleural fluid analysis can help confirm by showing a high glucose content consistent with PD solution.
