Pleuroperitoneal communication in a patient with right pleural effusion and ascites diagnosed by technetium-99m sulfur colloid imaging

A 55-year-old man with an 11-year history of intermittent right pleural effusions had continued fevers and a large right transudative pleural effusion. Minimal ascites was noted by ultrasound examination. A communication between the thorax and intraperitoneal cavity was established by radionuclide examination of the chest and abdomen. Tc-99m sulfur colloid was injected into the peritoneal cavity, and imaging at 1 and 4.5 hours confirmed passage from the peritoneal to the pleural cavity. Repeated attempts to sclerose the pleural cavity failed to decrease the transudative accumulations. The patient was subsequently treated with the placement of a LeVeen shunt.
