Diagnosis of peritoneal-pleural communication by peritoneography with (99m)Tc-sulfur colloid in a 3-year-old girl with congenital nephrotic syndrome of the Finnish type.

Around 5% of patients receiving renal replacement therapy in Spain are on peritoneal dialysis. Anatomical integrity of the peritoneum is essential since increased hydrostatic pressure due to peritoneal accumulation of dialysis fluid predisposes to abdominal or pelvic hernias or chest leakage via the embryonic pneumatoenteric recess.1 We report the case of a 3-year-old girl with a history of Finnish-type congenital nephrotic syndrome, receiving postnephrectomy peritoneal dialysis since the age of 2. Fourteen months after starting peritoneal dialysis, she was admitted to our hospital due to severe dyspnea, with massive right hydrothorax on chest X-ray. To rule out pleuroperitoneal leak, a peritoneal
