Female 33 years old Reason: ASSESS for possible occult sesamoid bone fracture of the left foot. History: Pain and swelling There is a bipartite medial hallux sesamoid bone, the margins of which are more suggestive of a normal variant rather than a fracture. There is minimal focal increased signal intensity on fluid sensitive sequences in the proximal ossicle which may be degenerative in nature but fatty marrow signal intensity is largely preserved on T1 weighted images. The lateral hallux sesamoid appears normal. Intermediate signal intensity of the intersesamoidal ligament could represent degeneration but alignment of the sesamoid bones is normal. Sesamoid phalangeal ligaments are intact. Flexor hallucis longus tendon is normal. Small amount of fluid is in joint, not necessarily of any significance. Between the first and second metatarsal heads there is a small amount of fluid in the bursa of questionable significance. The remainder of the visualized bones and soft tissues appear normal.
Bipartite medial hallux sesamoid bone with minimal degenerative signal changes in the proximal ossicle but no fracture is evident. Other findings as above.
