  • Background: Meningiomas are common intracranial tumors with a low metastatic rate. Those that do metastasize often show histopathologic signs of malignancy. In rare cases, the primary and secondary tumors are histologically benign.; Case Report: We report the case of a 57-year-old female with a histologically benign intracranial meningioma that metastasized to the sacrum. The patient had a long history of intracranial meningioma with multiple recurrences. At each recurrence, histopathologic examination of the resected tumor showed no signs of malignancy. The sacral meningioma was biopsied and found to be histologically benign. The patient was treated with radiotherapy (54 Gy in 30 fractions), and her symptoms resolved. Six months later, the patient developed left leg weakness. Magnetic resonance imaging showed growth of her intracranial mass for which she underwent a craniotomy for tumor resection. Pathologic evaluation showed evidence of benign meningioma without atypical features. She recovered well from this procedure and returned to her baseline in several weeks.; Conclusion: After treatment, the patient had no signs of radiographic progression in either location.
