T1-weighted MR images demonstrating an intermediate signal, with a few areas of a low signal, and a large, well-defined, lobulated, oval-shaped mass measuring 3.0 cm in proximal–distal, 2.6 cm in anteroposterior, and 3.1 cm in medial–lateral dimensions. The mass is present in the deep subcutaneous soft tissues of the palmar aspect of the hand, at the level of the second proximal phalanx, in a close proximity to the second flexor digitorum tendon. MR: magnetic resonance.
