MELTING ICE(CUBE) SIGN

By Dr Deepu

 The melting ice(cube) sign describes the resolution of. pulmonary haemorrhage following pulmonary embolism. 
When there is pulmonary haemorrhage without infarction following PE, the typical wedge-shaped, pleural-based opacification (Hamptons Hump) resolves within a week while preserving its typical shape. It is named due to its resemblance with a melting ice cube.
