Ultrasound documentation of diaphragmatic rent in hepatic hydrothorax.

Two patients with alcoholic cirrhosis of the liver with ascites were evaluated for the pathogenesis of right sided massive pleural effusion. The clinical course of events suggested a large communication between the peritoneal space and right pleural cavity. Real time ultrasonography revealed evidence of a tear in the right hemidiaphragm. The role of ultrasound in the documentation of cause of hydrothorax in chronic liver disease is highlighted.
