Edema and thickening along the ulnar side of the pulley and edema between the flexor pollicis longus tendon and the thumb proximal phalanx are redemonstrated. The appearance in this patient is compatible with annular pulley partial tear.
There is also bone marrow edema/contusion at the head of the first metacarpal bone.
Case Discussion
In acute mild pulley injury or partial tear, edema is seen along the course of the involved pulley in the sagittal view and pulley edema or irregularity may be directly visualized on the axial plan.
