1. To review to spectrum of accessory ossicle and sesamoid bones in the foot. 2. To recognize pathology associated with accessory ossicle and sesamoid bones in the foot. 3. To suggest appropriate imaging modalities and discuss imaging pitfalls.

Anatomic variant accessory ossicles of the foot will be reviewed by radiograph, CT, and high resolution MR imaging, with sample cases including: os peroneum, os subfibulare, os subtibiale, os tibiale externum (accessory navicular), os trigonum, os calcaneus secundarius, and os intermetatarseum.
