Intraosseous meningioma is an extremely rare benign tumor. We present the 68 Ga-fibroblast activation protein inhibitor (FAPI) PET/CT findings of primary intraosseous meningioma in a 71-year-old woman. 68 Ga-FAPI PET/CT revealed an intraosseous mass in the right parietal bone with increased FAPI activity. Primary skull malignancy was suspected. However, pathological examination after resection of the mass in the right parietal bone confirmed the diagnosis of benign meningioma (WHO I). A final diagnosis of benign intraosseous meningioma was made.
骨内脑膜瘤是一种极为罕见的良性肿瘤。我们报告一例 71 岁女性原发性骨内脑膜瘤的 68Ga-成纤维细胞激活蛋白抑制剂（FAPI）PET/CT 表现。68Ga-FAPI PET/CT 显示右侧顶骨内有一骨内肿块，FAPI 活性增高。考虑原发性颅骨恶性肿瘤。然而，右侧顶骨肿块切除后的病理检查证实为良性脑膜瘤（WHO I 级）。最终诊断为良性骨内脑膜瘤。
