MR – The lateral sesamoid bone is hypointense on T1 and hyperintense on FS-T2, IR and FS-T1 postgadolinium sequences. Minimal fluid is present in the first metatarsophalangeal joint.


Sesamoiditis is a painful inflammatory condition produced by repetitive injury to the plantar aspect of the forefoot. MR imaging findings in the marrow of the sesamoid bones include decreased or normal signal intensity on T1-weighted images and increased signal intensity on STIR images. Reactive soft-tissue abnormalities including tendinitis, synovitis, and bursitis are characteristic findings in sesamoiditis. Turf toe, plantar plate dysfunction, and stress change are important differential considerations.
