It is difficult to be certain whether this represents an old avulsion injury or an accessory ossicle (sub fibulare). The Peroneus Longus Muscle is attached to the fibula and is innervated by the fibular nerve. When correlated with surgical findings, findings at MR imaging were correct in 12 tendons. Some cases of peroneus longus calcification have been reported [3, 18]; however, all reports revealed calcification of the peroneus longus tendon at the cuboid level.
