Key clinical message: Pleuroperitoneal leaks are rare and normally arise as an early complication in peritoneal dialysis. This case illustrates the importance of considering pleuroperitoneal leaks as a cause for pleural effusions-even if peritoneal dialysis has been longstanding and uncomplicated.
Abstract: A 66-year-old male on peritoneal dialysis for 15 months presented with dyspnoea and low ultrafiltration volumes. Chest radiography revealed a large right-sided pleural effusion. Pleural fluid sampling and peritoneal scintigraphy confirmed a pleuroperitoneal leak.
Keywords: peritoneal dialysis; peritoneal scintigraphy; pleural effusion; pleuroperitoneal leak.
