摘要
目的探讨原发性额顶骨内上皮细胞型脑膜瘤的CT和MRI表现。方法回顾性分析经手术和病理证实的6例原发性额顶骨内脑膜瘤病人的CT和MRI表现,并结合病理学特征以及相关文献进行分析。结果病理检查显示,6例肿瘤均为上皮细胞型脑膜瘤,为WHOⅠ型;病灶均单发,位于额顶骨内,呈膨胀性生长。CT平扫病灶呈高密度,密度均匀;MRI表现为等T_1等T_2信号为主,信号均匀,增强扫描病灶呈明显均匀性强化,其中5例病灶相邻脑膜受推压、增粗,强化明显,4例病灶见脑膜尾征。结论良性额顶骨内脑膜瘤CT及MRI征象缺乏特异性,最终确诊须依靠病理学检查。
Objective To investigate the computed tomography（CT）and magnetic resonance imaging（MRI）findings of primary intraosseous meningothelial meningioma of the fronto-parietal bone. Methods A retrospective analysis was performed on the CT and MRI findings of 6 patients with pathologically confirmed primary intraosseous meningioma of the fronto-parietal bone.And then a comprehensive analysis was performed on the tumors based on the imaging findings,pathological features,and related literature review. Results The pathological examination showed that the tumors of all the 6 cases were meningothelial meningioma WHO Ⅰ;all the lesions were solitary and located in the fronto-parietal bone showing expansive growth.Plain CT scan showed a high and homogeneous density;MRI showed isointensity on T_1-weighted and T_2-weighted images;contrast-enhanced CT scan showed homogeneous enhancement.The adjacent meninges were pushed,thickening,and obviously enhanced in 5 cases,and dural tail sign was observed in 4 cases. Conclusion Benign primary intraosseous meningothelial meningioma of the fronto-parietal bone shows no specific manifestations in CT and MRI findings,so the final diagnosis should be confirmed by histopathological and immunohistochemical examinations.
