BACKGROUND
Osteolipomas are distinguished from other intracranial lipomas by their arrangement of central adipose and peripheral osseous tissues and by characteristically arising in the suprasellar/interpeduncular region.
METHODS
We report computed tomography (CT), magnetic resonance imaging (MRI), and pathology findings from this 34-year-old man who underwent surgical removal of this benign lesion.
RESULTS
This case displays the distinctive histopathology that has been reported in 13 of 31 (42%) lipomas in this region. In contrast, ossification of lipomas at other intracranial sites is relatively rare.
CONCLUSIONS
Ossification should be expected in many suprasellar/interpeduncular lipomas, and osteolipoma should be included in the radiologic differential diagnosis of fat-intensity masses with calcification in this region.
背景
骨脂肪瘤与其他颅内脂肪瘤的区别在于其中心脂肪组织和外周骨组织的排列方式，以及其特征性地起源于鞍上/脚间区域。
方法
我们报告了一名34岁男性的计算机断层扫描（CT）、磁共振成像（MRI）及病理检查结果，该患者接受了该良性病变的手术切除。
结果
本病例显示了该区域31例脂肪瘤中13例（42%）所报告的独特组织病理学特征。相比之下，其他颅内部位脂肪瘤的骨化相对少见。
结论
许多鞍上/脚间脂肪瘤应考虑存在骨化，骨脂肪瘤应纳入该区域具有钙化的脂肪密度肿块的放射学鉴别诊断中。
