摘要
目的:探讨颅骨板障型脑膜瘤的CT和MRI影像表现。方法:收集2012年1月至2013年6月经病理及免疫组化证实的颅骨板障型脑膜瘤病例共2例,分析其临床、病理及CT表现。结果:发生于额颞顶骨交界部1例、顶骨1例,病理证实前者为透明细胞型、后者为上皮型。前者为成骨性骨质破坏,CT表现为颅骨骨质明显增厚,边缘毛糙,内外板界限不清,部分病变内侧可见弧形钙化;后者为溶骨性骨质破坏,MRI表现为T1WI等低信号,T2WI等信号,增强扫描强化明显、均匀。结论:CT和MRI能对不同骨质破坏方式的板障型脑膜瘤的大小、形态和周围组织的侵犯程度作出较准确的诊断。
Objective： To assess the imaging finding of CT and MRI in intradiploic meningioma of skull. Methods： The clinical symptoms, pathological type and imaging finding of two cases were analyzed. Results： One of the intradiploic meningioma was located in the frontal temporal bone and the pathological type was clear cell meningioma. Its imaging finding of CT showed osteogenic destruction and the skull was thicken, edge is coarse. Another was located in parietal bone and the pathological type was Epithelial type. Its imageology was lytic bone destruction and T1 WI showed low signal or equisignal intensity, T2 WI was equisignal intensity. The signal of enhance scan improved significantly. Conclusion： CT and MRI can play an important role in diagnosing intradiploic meningioma. The size and surroundings of tumor can show by them accurately.
