35-year-old female with an III-MP type coalition involving both the middle and posterior facets. (A) The tarsal sinus (black arrow) can be seen and both overgrown talus and calcaneus (white arrows). (B) An accessory ossicle (white arrow) locates at the medial and inferior aspect of the talus and superior aspect of the calcaneus. The sclerosis is not found at the border between the ossicle and calcaneus or talus. (C) 3D reconstruction image shows that an accessory ossicle (circle) separates the talus and calcaneus
