Reason: eval for sesamoiditis History: medial sesamoid pain Note is made of a bipartite medial sesamoid bone of the first MTP joint, a normal anatomic variant. However, there is associated decreased signal abnormality within the medial sesamoid bones on all pulse sequences indicating sclerosis likely related to osteonecrosis. There is no increased signal abnormality and fluid sensitive sequences to suggest an acute sesamoiditis. The lateral sesamoid bone of the first MTP joint is normal in appearance. Otherwise no bone marrow signal abnormality is identified. The remainder of the imaged soft tissues of the foot are unremarkable. The flexor and extensor tendons appear intact.
Findings suggestive of osteonecrosis of a bipartite medial sesamoid bone of the first MTP joint as described above.
