37-year-old male with rapidly growing left wrist mass on dorsum. Evaluate left wrist cyst. Evaluation of the wrist is limited due to patient motion artifact and inability to use a dedicated wrist coil. The patient refused repeat imaging.A marker was placed along the dorsum of the wrist. There is a dumbbell-shaped mass situated within the soft tissues of the wrist dorsal to the scaphocapitate articulation and situated between the tendons of the second and fourth extensor compartments. It is approximately 14 mm x 11 mm in greatest transverse dimension and approximately 15 mm in longitudinal dimension. It is isointense to skeletal muscle on T1-weighted images and hyperintense to skeletal muscle on T2-weighted images. It is lobulated with internal septations. We see no additional soft tissue masses, although there is prominent vasculature presumably related to the patient's vascular graft not visualized on this study. Given the limitations of the study, the remaining soft tissues appear normal as do the bones.
Limited study as described above showing a lobular mass in the dorsal soft tissues of the wrist. Statistically this is most likely a ganglion, particularly based on its lobulated morphology, however lack of intravenous contrast administration limits further evaluation of the mass.
