We present a rare case of the primary intracranial melanoma in the right parafalcine frontal region in a 65-year-old male. Computed tomography and magnetic resonance imaging showed a Space occupying lesion in the right parafalcine frontal region with necrosis, vasogenic edema and mass effect. A rather well-defined, dark brown-black tumor was totally removed and histologically diagnosed as malignant melanoma. The patient improved after surgery. In our case, no systemic melanomas were found in close clinical examinations, there was a single nodular tumor attached to the leptomeninges and a favorable outcome was obtained by surgical treatment alone. Primary central nervous system melanomas have rarely been reported, and this case is reported for its rarity.
我们报告了一例罕见的原发性颅内黑色素瘤病例，发生在一名65岁男性的右侧大脑镰旁额叶区域。计算机断层扫描和磁共振成像显示右侧大脑镰旁额叶区域有一个占位性病变，伴有坏死、血管源性水肿和占位效应。一个边界相当清晰的深棕色至黑色肿瘤被完全切除，组织学诊断为恶性黑色素瘤。患者术后病情好转。在我们的病例中，经过仔细的临床检查未发现全身性黑色素瘤，仅有一个附着于软脑膜的结节状肿瘤，仅通过手术治疗就取得了良好的效果。原发性中枢神经系统黑色素瘤鲜有报道，本病例因其罕见性而被报告。
