TEACHING POINTS

1. Many palpable masses of the hand and wrist are of non-neoplastic origin. 2. The differential diagnosis of palpable masses of the hand and wrist can be narrowed by identifying their relationship to surrounding structures and defining the signal characteristics on MR imaging. 3. A more definitive diagnosis can be reached when the physical exam findings and previous medical conditions are known.
