Inomo T, Aoyama M, Maejima R, Hara M. Spinal meningeal melanocytoma with direct bone metastasis: A case report and literature review. Int J Case Rep Images 2023;14(2):80–84.ABSTRACT
Meningeal melanocytoma is a rare benign tumor of the central nervous system. An intradural extramedullary tumor at C2 was accidentally discovered in a 58-year-old woman six years ago. The lesion was well-circumscribed mass on computed tomography and magnetic resonance imaging. We predicted the tumor to be a meningioma. We performed tumor resection because its gradual growth compressed the spinal cord. Intraoperatively, the tumor was dark brown and the nearby dura matter and the lamina had a pigmented lesion suggesting direct invasion. After gross total removal, the tumor was diagnosed as meningeal melanocytoma by pathological examination. Meningeal melanocytoma with direct bone metastasis are rare. We present this case with reference to previous literature.
