Enchondroma protuberans of the hand.

Abstract

Enchondroma protuberans is a rare tumor that arises from an intramedullary enchondroma with an exophytic growth pattern. The purpose of this study was to describe imaging findings of this disease that were obtained using both radiography and MRI. It is necessary to understand the characteristic imaging findings of enchondroma protuberans to avoid misdiagnosis. When radiography does not allow a clear diagnosis of enchondroma protuberans, MRI may be helpful for diagnosis.
