Abstract:
A case of meningeal melanocytoma, the 14th in the literature, is presented. Neurodiagnostic imaging, with both computed tomographic scan and magnetic resonance imaging, is included. Pathological examination of the tumor consisted of light microscopy, electron microscopy, and immunohistochemistry. The literature is reviewed and pathological criteria are presented to distinguish meningeal melanocytoma from meningiomas containing melanin pigment and from malignant melanoma.
