Malign melanoma of the nasal cavity that arises at such an unusual location is an exceptional case only occasionally mentioned in the literature. An amelanotic form, which is an uncommon type for this malignancy, also has an unusual radiological appearence from the classic melanotic form. We report here the magnetic resonance imaging (MRI) findings of a 46-year-old man who had a nasal cavity mass diagnosed as an amelanotic malign melanoma and discuss the importance of differential diagnosis with such an unusual radiological manifestation in this location.
鼻腔恶性黑色素瘤发生在如此不寻常的部位是一个例外情况，在文献中仅偶尔被提及。无色素型是这种恶性肿瘤的一种不常见类型，其影像学表现也与典型的色素型不同。我们在此报告一名46岁男性鼻腔肿物的磁共振成像（MRI）表现，该肿物被诊断为无色素性恶性黑色素瘤，并讨论在这个部位出现这种不寻常影像学表现时进行鉴别诊断的重要性。
