Figure 4: (a) Axial T1-weighted magnetic resonance images of the left wrist at the level of the distal radio-ulnar joint showing two separate well-defined isointense lesions involving the flexor digitorum profundus tendon sheath of the 2nd digit (long arrow) and the 3rd to 5th digits (short arrow). (b-d) Axial T2 short ti inversion recovery magnetic resonance images of the left hand at the level of carpal tunnel (b), just distal to the tunnel (c) and farther from the tunnel (d) showing hyperintense lesions along the sheath of flexor pollicus longus tendon (thick arrow) and flexor digitorum superficialis tendon of the 4th and 5th digits (thin arrow). Along the dorsum, a similar hyperintense lesion with internal dot-like hypointensities representing synovial proliferation can be seen along the sheaths of extensor digitorum tendon involving the 3rd and 4th tendon slips (striped arrow)
