We report a case of cemento-ossifying fibroma that presented as a large extraosseous mass in the masticator and parapharyngeal space. CT scanning and MR imaging showed a large extraosseous mass with central conglomerated, well-matured ossified nodules and fatty marrow. The central matured ossified nodules were of low density on CT scans and high signal intensity on T1- and T2-weighted MR images. Multiplanar reformatted CT scans revealed the origin of the mass to be at the extraction site of the right lower second molar tooth.
我们报告一例骨化纤维瘤,表现为咀嚼肌和咽旁间隙的巨大骨外肿块。CT扫描和磁共振成像显示一个巨大的骨外肿块,中央有聚集的、成熟良好的骨化结节和脂肪骨髓。中央成熟的骨化结节在CT扫描上呈低密度,在T1加权和T2加权磁共振图像上呈高信号强度。多平面重建CT扫描显示肿块起源于右下第二磨牙的拔牙部位。
