Abstract

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.

종자골과 부골은 정상 해부학적 변이로 그 빈도와 형태는 다양하며 일반적으로 크기가 작고 둥근 모양으로 피질로 잘 둘러싸여 있고 뼈나 관절 주위에 인접하여 관찰되고 드물게 이분 혹은 다분 형태를 보일 수 있다. 대부분의 종자골과 부골은 무증상이며 판독 업무 중에 흔히 마주치게 된다. 하지만 때때로 종자골과 부골이 증상을 일으킬 수 있는데, 종자골과 부골 자체의 골절이나 탈구, 관절염, 골괴사, 감염 등의 질환이 이환되거나, 주변에 신경압박이나 건초염, 연부조직의 포착 등에 의하여 증상을 유발할 수 있다. 이 종설에서는 다양한 해부학적 위치에서 발생한 증상이 있는 종자골과 부골의 영상을 보고, 이들의 임상적 양상과 영상의학적 감별진단을 정리해보고자 한다.
