Figure 16: Calcific tendinitis of the flexor hallucis brevis. (a) and (b) Amorphous calcification consistent with acute, symptomatic phase of calcific tendinitis is present just proximal to the hallucal sesamoids (arrows). (c) Long axis PD fat-saturated MR image shows heterogenous signal of the calcification (arrowhead) with mild surrounding edema, which is also consistent with acute symptomatic phase.
