Abstract

Parosteal lipoma is a rare benign tumor containing mature adipose tissue having an intimate relationship to the periosteum. Characteristically, this tumor presents as a lipomatous mass adjacent to bone, eliciting variable reactive changes in the underlying cortex. We report a case of parosteal lipoma of the foot. The MR findings consisted of juxtacortical lipomatous mass abutting to bony protuberance, with internal fibrous striations, and osseous reaction in the adjacent bone. By the aid of multiplanar imaging capability, high spatial and contrast resolution of MRI, characteristic features of parosteal lipoma can lead to diagnosis on imaging.

뼈주위 지방종은 골막과 밀접한 관련성을 지니며 발생하는 드문 양성지방종으로 조직소견은 전형적인 연부조직 지방종과 같은 성숙지방세포로 구성된다. 영상에서 특징적으로 뼈와 인접한 지방성의 덩어리로 나타나며 인접한 골피질에 다양한 반응성 변화를 일으킨다. 자기공명영상에서는 뼈주위에 위치한 양성지방종, 이와 연결된 뼈의 돌기 또는 반응성 골피질 변화, 또한 신경 압박에 의한 이차적 근육 퇴행 등의 소견을 관찰할 수 있다. 이 보고에서는 중족골에 연해 발생한 뼈주위 지방종의 증례를 자기공명영상 소견을 중심으로 기술하고자 한다.
