Primary diffuse leptomeningeal melanomatosis is a rare variant of malignant melanoma of the central nervous system, arising from melanocytes of leptomeninges. It may involve leptomeninges and may invade brain superficially. The diagnosis of the disease with conventional imaging techniques is quite difficult. This case demonstrates the F-FDG uptake of primary diffuse leptomeningeal melanomatosis matching with MRI contrast enhancement regions particularly in the lower thoracic and superior lumbar region.
原发性弥漫性脑脊膜黑色素瘤是中枢神经系统恶性黑色素瘤的罕见变异型，起源于脑脊膜的黑色素细胞。它可能累及脑脊膜，并可能在脑表面浸润。传统影像学技术对该病的诊断较为困难。本病例显示，原发性弥漫性脑脊膜黑色素瘤的 F-FDG 摄取与 MRI 对比增强区域相匹配，尤其是在胸下段和腰上段。
