Q.Explain Pericardial Effusion?

The configuration of the heart in pericardial effusion depends on the volume of fluid and its distribution. It may have a globular or non-specific shape. In large effusions, there is very often a localized bulge in the left upper cardiac border. There is striking absence of abnormalities of the pulmonary vasculature. The combination of a large heart, with clear rather than congested lungs suggests a pericardial effusion. A rapid change in heart size over serial films also may be seen.
