Hampton hump
From Infogalactic: the planetary knowledge core
Hampton's hump, also called Hampton hump, is a radiologic sign which consists of a shallow wedge-shaped opacity in the periphery of the lung with its base against the pleural surface.[1] It is named after Aubrey Otis Hampton, who first described it in 1940.[2] Hampton's hump along with Westermark sign may aid in the diagnosis of pulmonary embolism, although they are rare and their sensitivities and interoperator reliabilities are low.
