Abstract: Accessory ossicles are normal variants that are frequently seen but often overlooked or misdiagnosed. Commonly seen at the foot and ankle, they may be mistaken for fracture fragments or loose bodies, or not be recognised as a cause of the patient's symptoms. This pictorial essay aimed to review commonly encountered accessory ossicles of the foot and ankle by highlighting anatomic landmarks and associated pathologic processes through the use of both basic and advanced imaging modalities, in an effort to increase awareness of these clinical entities.
