Intraosseous lipomas are rare benign tumors of the bone, especially for the mandible. The etiology remains unclear, although several hypotheses have been proposed, such as trauma, blood vessel infarction, aging and inflammation. Clinically, the symptoms mainly depend on the location and size of the tumors. Radiographically, the lesions are usually radiolucent occasionally accompanied by radiopacity. The diagnosis is challenging, and histopathologic examination is necessary for definite diagnosis. Herein, the authors report an unusual patient with intraosseous lipoma in the mandibular condyle.
骨内脂肪瘤是一种罕见的骨良性肿瘤，尤其多见于下颌骨。其病因尚不清楚，尽管提出了几种假说，如外伤、血管梗死、老化和炎症。临床上，症状主要取决于肿瘤的位置和大小。影像学上，病变通常为透光性，偶尔伴有不透光性。诊断具有挑战性，需要组织病理学检查才能明确诊断。本文报道了一例下颌骨髁突骨内脂肪瘤的罕见病例。
