The mass was iso-intense in the T1 and hyper-intense in the T2 images (Fig. 1A). Surgical exploration showed a longitudinal mass attached to the volar aspect of the flexor superficialis tendon of the middle finger (Fig. 1B). Grossly, the mass was made up of a cystic cavity with a thick hyalinazed wall (Fig. 1C). The histopathological picture was consistent with a ganglion (Fig. 1D).
