"Signs are numerous in radiology and typically relate to a specific appearance or feature that is reminiscent of an object. A named sign aims to help recognise or understand a specific imaging appearance (e.g. racing car sign of corpus callosal dysgenesis). The most important signs are those that help radiologists recognise important and otherwise non-obvious diagnoses (e.g. sail sign of radial neck fractures or Mt Fuji sign of tension pneumocephalus)."
"the sign is not widely published in existing radiology or medical literature; a single case report is not sufficient"
"the sign is a variation on an existing sign (e.g. bullseye vs target); in such instances, it can be added as a synonym"
"the sign is racist, sexist, offensive or otherwise inappropriate: see unacceptable content"
