摘　　要：目的分析恶性黑色素瘤的CT表现,探讨CT诊断的价值。资料与方法回顾分析20例经手术病理证实的恶性黑色素瘤的CT表现。结果鼻腔及鼻窦中的9例肿瘤CT表现均为单侧无钙化软组织肿块,部分伴邻近结构侵犯;眼球2例表现为球内高密度占位;颅内1例为类圆形等密度灶,增强扫描强化明显;上颌骨、咽部、硬腭病灶为不规则软组织肿块;转移4例具备转移瘤特点。结论CT对恶性黑色素瘤的定性有一定限度,但可清晰显示病变范围、部位、侵犯及骨质破坏情况,对临床确定治疗方案及判断预后有重要作用。Objective To discuss the diagnostic value of CT in malignant melanoma.
