目的：探讨颅内脑膜瘤CT表现，并提高其诊断准确率。方法回顾性分析55例经病理证实的脑膜瘤临床及影像资料，与手术、病理结果进行对照，总结、归纳脑膜瘤CT影像特点。结果肿瘤呈高密度者46例，呈等密度5例，呈混合密度有4例，邻近颅骨出现骨质增生硬化29例，瘤周水肿7例，45例肿瘤边缘清楚，10例肿瘤组织与周围脑组织边缘不清。增强扫描后病灶明显均匀强化者47例，明显不均匀强化2例，轻度强化3例，强化不明显2例，肿瘤周边薄层环状强化影1例。结论脑膜瘤典型CT表现为位于脑外，呈宽基底与硬脑膜或颅骨相连，呈等或稍高密度、较均匀，增强后明显均匀强化，抓住以上特点有助于术前明确诊断。

Objective To explore the CT imaging features of intracranial meningiomas, and improve the diagnostic accuracy. Methods The clinical and imaging data of 55 cases of intracranial meningiomas which confirmed by pathology were analyzed retrospectively, and compared with surgery and pathology, and summarize the CT imaging features of intracranial meningiomas. Results Forty-six cases showed high density, 5 showed iso-intensity, and 4 were mixed density, hyperostosis osteosclerosis of the skull could be seen in twenty-nine cases; edema around the tumor in twenty-two cases. Forty-five cases of tumor with clear edge, ten cases of tumor with blurry edge. 47 cases showed obvious homogeneous enhancement after enhanced, and 2 had inhomogeneous enhancement;three cases showed mild enhancement; two cases had no enhancement. Ring-like enhancement could be seen around the tumor. Conclusion The classical CT imaging features of the intracranial meningiomas is that the lesion located out of the brain, attached to the dura with wide substrate, showed iso-intensity or high density, and had obvious homogeneous enhancement after enhanced.
