Auenbrugger's sign

Auenbrugger's sign is a bulging of the epigastrium seen in cases of severe pericardial effusion. It is often not spotted because pericardial effusion can be caught on echocardiography before it progresses this far.^[1] It is named after Joseph Leopold Auenbrugger.^{[citation needed]}
