The pathophysiology is unknown, and it is usually associated with increased abdominal pressure. Upon pleural fluid analysis, a transudate with elevated glucose concentration is found, and the patients present with acute dyspnea, cough, and decrease in the ultrafiltration rate. We present the case of an 81-year-old woman with history of peritoneal dialysis presenting with recurrent pleural effusion. A peritoneal scintigraphy with 99m Tc was performed confirming the diagnosis of pleuroperitoneal fistula.enMedicinePeritoneal dialysisFistulaTransudatePleural effusionScintigraphyHydrothoraxSurgeryRadiologyarticle
