| 摘 要： | 目的探讨颅内外型舌下神经鞘瘤的MRI特点。方法回顾性分析经手术病理证实的4例颅内外型舌下神经鞘瘤的MRI表现。结果病灶均呈哑铃形，表现为局部软组织肿块阴影，在T1WI上呈等或稍低信号，T2WI呈稍高信号，增强后有明显的环状或不均匀强化，边界均较清晰，同时可见舌下神经孔扩大4例，见线条状增粗的舌下神经与病灶相连3例。结论颅内外型舌下神经鞘瘤具备较特征性的MRI表现。 |

| Abstract: | Objective To discuss MRI characteristics of intracranlal and extracranlal hypoglossal schwarmoma. Methods MRI fmdings of 4 cases with hypoglossal schwannoma verified by operation and pathology were analyzed retrospectively. Results All of 4 cases showed dumb-bell shapes. They all appeared as well-defined soft tissue mass which demonstrated isointensity or mild hypointensity on T1-weighted image and mild hyperintensity on T2-weighted image. Marked ring-like or inhomogeneous enhancement was showed after giving contrast media. Enlargement of hypoglossal nerve canal was revealed in all cases and enlarged hypogiossal nerve was found to connect to the tumor in 3 cases. Conclusion There are characteristic MRI appearances for intracranial and extracranial hypoglossal schwannoma. |
