Sesamoid bones and accessory ossicles are normal anatomic variants with varying morphological appearances and incidences. They are usually small osseous fragments with well-corticated margins located adjacent to the joint space and bone. Patients with sesamoid bones and accessory ossicles are usually asymptomatic and commonly encountered in clinical practice. These sesamoids and accessory bones are occasionally painful because of fractures, dislocations, degenerative changes, avascular necrosis, accessory bone infections, or abnormalities of the adjacent tissue, such as nerve entrapment, tenosynovitis, or soft tissue impingement. This article aimed to illustrate the imaging features of symptomatic sesamoids bones and accessory ossicles at various anatomic locations and describe their clinical features and radiological differential diagnosis.
籽骨和副骨是具有不同形态外观和发生率的正常解剖变异。它们通常是边缘皮质良好的小骨碎片，位于关节间隙和骨骼附近。患有籽骨和副骨的患者通常无症状，在临床实践中很常见。这些籽骨和副骨偶尔会因骨折、脱位、退行性改变、缺血性坏死、副骨感染或相邻组织异常（如神经卡压、腱鞘炎或软组织撞击）而疼痛。本文旨在阐述有症状的籽骨和副骨在不同解剖位置的影像学特征，并描述其临床特征和放射学鉴别诊断。
