A case of hepatic hydrothorax.

Hepatic hydrothorax occurred in a 38-year-old woman of severe hepatic failure complicated with pulmonary tuberculosis. The transdiaphragmatic passage of ascitic fluid to the pleural cavity was visually shown with a scintigram using technetium-99m macroaggregated albumin and also shown with a tracer analysis using indocyanine green. The ascites was suggested to be transported to the pleural cavity via the defect in the right diaphragm.
