Reason: characterize left wrist mass History: increasing in size left wrist mass, more proximal than typical ganglion There is a well-defined, nonenhancing lesion with multiple thin septa abutting the volar aspect of the distal radius, which measures 2.4 x 1.9 cm in its axial dimensions. The lesion is iso-intense to muscle on T1-weighted imaging and hyperintense on T2 weighted imaging. The bones, bone marrow, ligaments, and tendons are within normal limits.
Lesion abutting the volar aspect of the distal radius is most consistent with a ganglion cyst.
