Sesamoiditis. A 39-year-old woman, referred with the suspicion of sesamoiditis. Sagittal Fast FSE PD fat sat demonstrates increased signal intensity in both aspects of the sesamoid—metatarsal joint, with loss of cartilage and narrowing of the joint space (black arrows), as well as associated increased signal intensity in the subcutaneous tissue fat in the plantar aspect (white arrows). Findings are in keeping with degenerative change in joint, but there is added adventitial bursitis reaction
