Symptomatic os peroneum. a A 61-year-old woman, referred for lateral ankle pain. Sagittal proton density spectral attenuation inversion recovery (PD SPAIR). High signal intensity is present in the os peroneum (white arrow), in keeping with bone marrow edema. The peroneus longus tendon appears hyperintense (arrowheads). b On FSE T1, in a slightly more lateral plane, the increased signal intensity in the peroneus longus tendon is also evident (black arrowheads), proximal to the os peroneum, in keeping with tendinopathy
