Cutaneous melanomas rarely metastasize to the ovary; however, we have recently encountered three cases which have proved a diagnostic dilemma. All presented with a pelvic mass and a past history of cutaneous melanoma but both ultrasound examination and CT scanning proved inconclusive and neither was able to accurately characterize the lesions. Magnetic resonance imaging (MRI) was able to demonstrate the presence of melanin in one of the ovarian lesions as peripheral high signal change on T1-weighted images. The two lesions without melanin failed to show this feature. MRI may therefore be useful in the diagnosis of ovarian melanoma but only if melanin is present.
皮肤黑色素瘤很少转移至卵巢；然而，我们最近遇到了三例诊断困难的病例。所有病例均表现为盆腔肿块且有皮肤黑色素瘤病史，但超声检查和CT扫描结果均不明确，两者均无法准确描述病变特征。磁共振成像（MRI）能够在T1加权图像上显示其中一个卵巢病变中存在黑色素，表现为周边高信号改变。另外两个不含黑色素的病变未显示此特征。因此，MRI可能对卵巢黑色素瘤的诊断有用，但前提是存在黑色素。
