Accessory Ossicles and Sesamoid Bones: Spectrum of Pathology and Imaging Evaluation

Babak N. Kalantari, MD ; Leanne L. Seeger, MD ; Kambiz Motamedi, MD ; Kira Chow, MD

The authors describe a spectrum of accessory ossicle and sesamoid pathology and suggest appropriate imaging modalities. While they are considered to be normal anatomic variants, accessory ossicle and sesamoid bones may help to identify the source of patient symptomatology. The recognition of key imaging findings can help radiologists determine whether or not clinical symptoms are associated with these structures.
