초록
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.
