Abstract：
BACKGROUND: Meningeal melanocytoma is a rare benign pigmented tumor originat from leptomeningeal melanocytes. Here, we report the case of a female who presented with numbness and weakness of the limbs for approximately 6 months.
METHODS: We report the case of a 60-year-old Chinese female who presented with numbness and weakness of the limbs for approximately 6 months. computed tomography (CT) and magnetic resonance imaging (MRI) revealed a dumbbell-shaped tumor inside and outside the cervical (C) spinal canal.
METHODS: The patient was using CT and MRI. Subsequently, the patient underwent surgery, and low-grade melanocytoma was diagnosed pathologically.
METHODS: Subsequently, the patient underwent a surgery, and the tumor was completely removed.
RESULTS: The tumor did not recur after 6 months.
CONCLUSIONS: This case suggested 2 \"take-away\" lessons: first, spinal meningeal melanocytomas may be dumbbell-shaped; and second, melanocytoma could appear as hyperintense, isointense, or hypointense on T2-weighted MRI.

摘要：
背景：脑膜黑素细胞瘤是一种罕见的良性色素肿瘤，起源于软脑膜黑素细胞。这里,我们报告了一例女性，她出现了大约6个月的麻木和四肢无力。
方法：我们报告了一例60岁的中国女性，她出现了大约6个月的麻木和四肢无力。计算机断层扫描（CT）和磁共振成像（MRI）显示颈椎（C）椎管内外的哑铃形肿瘤。
方法：患者进行CT和MRI检查。随后，病人接受了手术,病理诊断为低度黑色素细胞瘤。
方法：随后，病人接受了手术,肿瘤被完全切除了.
结果：6个月后肿瘤没有复发。
结论：此案例建议2“take-away”课程：首先，脊髓脑膜黑素细胞瘤可能是哑铃形的；其次，黑素细胞瘤可能表现为高强度，等强度,或在T2加权MRI上为低信号。
