Protean in standard English has the meaning of something that appears in many different forms. In the same vein, in radiological usage it is used to describe a condition which can assume multiple different guises. One of its classic uses is for the imaging appearance of osteomyelitis which can look like virtually anything.

It is derived from a name (see below) and therefore may be capitalized or non-capitalized.

Occasionally in medicine the term 'legion' is used in a similar manner. Legion used in this way means a "large number of".

History and etymology

From the Ancient Greek name Proteus, a god of the sea who was a shapeshifter, and therefore could take on an infinite variety of appearances 1.
