11 year old male with right heel pain and previous abnormal MRI. There is minimal patchy edema-like signal and enhancement within the talus and calcaneus, appearing similar to that seen on prior study. Mild patchy edema-type enhancement in the navicular and middle cuneiform appears new when compared to the previous study. A tiny focus of high signal intensity seen within the body of the calcaneus laterally, posterior to the subtalar joint, measures approximately 2mm and shows mild enhancement following gadolinium administration, and is new from the prior study. Note is made of a peroneus quartus, a normal variant. The remaining soft tissue structures appear normal. There is a small amount of fluid in the tibiotalar and subtalar joints. A small amount of fluid also extends outward from the sinus tarsus along the extensor retinaculum. We see no fracture.
Mild patchy bone marrow edema-like signal as described above, new in the navicular and middle cuneiform. This is often a "normal" finding in children and adolescents and may represent relatively active hematopoietic marrow. Stress reactions are considered less likely.
