Accessory Ossicles and Sesamoid Bones Spectrum of Pathology and Imaging Evaluation

Description: 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.
Sesamoid bones evaluated include - # Os Acromiale # Os Styloideum (Carpal Boss) # Sesamoid Bones of the Hand # Patella # Os Trigonum # Os calcaneus secundarius # Accessory Navicular (Os Tibiale Externum, Os Naviculare Secundarium) # Os Peroneum # Os Intermetatarseum # Hallux Sesamoids
