title: Ascites and right pleural effusion: demonstration of a peritoneo-pleural communication.
abstract: A 54-yr-old female with known liver cirrhosis presented with a right transudative pleural effusion and ascites. To find the source of pleural fluid, [99mTc]sulfur colloid was injected intraperitoneally and a serial imaging study revealed its passage to the right pleural space on 2-hr and 24-hr images. Mechanisms proposed in the formation of pleural effusion in liver cirrhosis are (a) lymphatic drainage and (b) diaphragmatic defect. Radioisotope migration speed may be a clue for differentiating these two mechanisms, being more rapid in the presence of a diaphragmatic defect.
