Melting ice cube sign (lungs)

Last revised by Craig Hacking on 31 May 2018

The melting ice cube sign describes the resolution of pulmonary hemorrhage following pulmonary embolism (PE)

When there is pulmonary hemorrhage without infarction following PE, the typical wedge-shaped, pleural-based opacification (Hampton's hump) resolves within a week while preserving its typical shape. It is named due to its resemblance with a melting ice cube 1.
