Chordoma - clivus

Case contributed by A.Prof Frank Gaillard

A high T2 signal mass arises from the posterior surface of the clivus and indents the pons. This has been likened to a thumb and the term "thumb sign" has even been proposed. It is said to be relatively specific for a chordoma in the correct clinical and imaging setting.
