Pleuroperitoneal Leak as an Uncommon Cause of Pleural Effusion in Peritoneal Dialysis: A Case Report and Literature Review

Abstract EN

Pleural effusions are frequently seen in patients on dialysis.

A pleuroperitoneal leak or communication is a rare but important cause of pleural effusion in patients on peritoneal dialysis.

This diagnosis can be made with a combination of biochemical tests and radiological modalities, in the absence of a gold standard diagnostic test.

In addition to thoracocentesis, treatment often involves cessation of peritoneal dialysis and transition to hemodialysis.

We describe a case of an 80-year-old man who presented with unilateral right-sided pleural effusion.

He underwent therapeutic thoracocentesis and was subsequently diagnosed with a pleuroperitoneal leak through pleural fluid analysis.

Peritoneal dialysis was ceased, and he transitioned temporarily to hemodialysis.

He was subsequently treated with talc pleurodesis and successfully recommenced on peritoneal dialysis at six weeks after operation.

In our report, we also review diagnostic imaging modalities, as well as advantages and disadvantages of each modality.

A pleuroperitoneal leak is a rare but important complication of peritoneal dialysis and needs consideration in any patient on peritoneal dialysis presenting with unilateral pleural effusion.
