Left-sided pleural effusion secondary to continuous ambulatory peritoneal dialysis

A young woman with diabetes mellitus and subsequent renal insufficiency developed a massive left-sided pleural effusion secondary to continuous ambulatory peritoneal dialysis (CAPD). There was no increase in weight, and she was free from oedema and fever. Thoracocentesis yielded a clear, yellow fluid with isolated leucocytes and mesothels, but no atypical cells. A cannulogram via a Tenckhoff catheter showed a satisfactory catheter function and position. CAPD, even when properly performed with correct catheter position, may result in massive pleural effusion.
