From: Axial osteitis of the proximal sesamoid bones and desmitis of the intersesamoidean ligament in the hindlimb of Friesian horses: review of 12 cases (2002-2012) and post-mortem analysis of the bone-ligament interface

Figure 1

Low-field (0.27 T) MR imaging of the MTPJ. A) T1 weighted GRE transverse image at the level of the PSBs and ISL. B) STIR transverse image at the same level. C) T1 weighted GRE dorsal image. The proximal part of the ISL shows an iso-intense signal compared to surrounding tissues on T1 weighted GRE images (A, C, white line marked area) and an irregular hyperintense signal on STIR images (B, white line marked area). A slightly ill-defined increase in signal intensity was also present at the proximo-axial aspect of the compact bone of the PSBs and extending slightly into the spongiosa on all sequences. The margins of the compact bone are irregular. Note the diffuse hypointense signal of the PSBs on the T1-weighted images (A, C). These findings may be consistent with inflammation and fibrous tissue (scar) formation in the ligament and adjacent region, loss of compact bone at the proximo-axial aspect and edema in the adjacent spongious bone of the PSBs.
