目的:分析鼻腔鼻窦沟通性脑膜瘤的影像学表现,提高对特殊类型脑膜瘤的认识。方法:对4例经手术和病理证实的鼻腔鼻窦沟通性脑膜瘤的影像及有关临床资料进行回顾性分析。结果:肿瘤形态呈分叶结节状,大小不一,瘤体跨越鼻咽及颅腔,伴有均匀明显强化;部分颅底局部解剖腔(孔)变形或扩大、颅底骨质局限性吸收、增生硬化。结论:沟通性脑膜瘤首次诊断有一定的困难,仔细分析肿瘤的起源部位和影像特点有助于作出正确的诊断。
Objective: To analyze the imaging manifestations of nasal sinus communicating meningioma and to improve the understanding of special types of meningioma. Methods: Four cases of nasal sinus communicating meningioma confirmed by operation and pathology were retrospectively analyzed. Results: The tumor morphology showed lobulated nodules with different sizes. The tumor spanned the nasopharynx and cranial cavity with obvious enhancement. Some of the skull base local anatomic cavities (holes) were deformed or enlarged, and the skull base was limitedly absorbed. Hypertrophic sclerosis. Conclusion: The first diagnosis of communicable meningioma has some difficulties. Careful analysis of the tumor’s origin and imaging features can help to make the correct diagnosis.
