Primary intraosseous lytic meningiomas are rare tumors, with only 16 cases described in the literature. We present a case in which CT and MR imaging with contrast agent helped diagnose preoperatively an enlarging skull mass as a primary intraosseous lytic meningioma in a 70-year-old woman. Radiographic findings revealed a lytic mass centered on the coronal suture line that separated and thinned both the outer and inner tables of the frontal bone.
原发性骨内溶骨性脑膜瘤是罕见肿瘤，文献中仅描述了16例。我们报告一例，通过CT和增强磁共振成像，术前诊断出一名70岁女性颅骨上一个不断增大的肿块为原发性骨内溶骨性脑膜瘤。影像学检查结果显示，一个以冠状缝为中心的溶骨性肿块，该肿块使额骨的内外板分离并变薄。
