Figure 13c. Dorsal ganglion in a 25-year-old woman who presented with a painful soft-tissue mass. (a, b) Sagittal (a) and coronal (b) T2-weighted MR images reveal a well-defined mass with high signal intensity and a mildly lobulated contour (short arrow) adjacent to the fourth extensor tendon (long arrows in a). (c) On a coronal gadolinium-enhanced fat-suppressed T1-weighted MR image, the mass demonstrates low signal intensity with peripheral enhancement (arrows).
