目的:探讨多发脑膜瘤的影像学特点。方法:对27例经术后病理确诊的多发性脑膜瘤患者术前影像学等临床相关资料进行回顾性分析。结果:本组27例中,共58个病灶,颅内病灶最多的共有14个,最少的共有2个,显示大脑凸面肿瘤数27个,大脑镰13个。肿瘤实体直径最小为0.5 cm,最大为8.5 cm,平均4.5 cm。其中78%(21例)发病模式为一个较大肿瘤和许多较小肿瘤,仅有6例为大小相似的2个或多个肿瘤,并且肿瘤总数均小于5个,数目较多的肿瘤为“子母瘤”的形式。结论:多发脑膜瘤的数目、大小差别较大,既可集中分布,亦可分散存在,无论是多排增强CT还是高场强MRI诊断均应全面观察,避免遗漏。
Objective: To investigate the imaging features of multiple meningioma. Methods: The clinical data of 27 cases with multiple meningioma confirmed by postoperative pathology were analyzed retrospectively. Results: A total of 58 lesions were found in 27 cases of this group. There were 14 cases of the most intracranial lesions with a minimum of 2 cases, showing 27 cases of cerebrum convex tumors and 13 cerebral falx. The smallest diameter of the tumor is 0.5 cm and the largest is 8.5 cm with an average of 4.5 cm. Among them, 78% (21 cases) had a larger tumor and many smaller tumors. Only 6 of them were 2 or more tumors of similar size with less than 5 tumors. The larger number of tumors were The form of “child tumor”. Conclusions: The number and size of multiple meningiomas vary greatly. They can not only concentrate but also disperse. Whether multi-row enhanced CT or high field MRI should be comprehensively observed to avoid omission.
