We present a case of malignant melanotic neuroectodermal tumor of infancy arising in the skull and secondarily invading brain. The central tumor was hyperintense to brain on T1-weighted images and hypointense to brain on T2-weighted images. This appearance corresponded to the surgical and histologic findings of melanin-containing tumor.
我们报告一例发生于颅骨并继发侵犯脑的婴儿恶性黑素性神经外胚层肿瘤。中央肿瘤在T1加权像上相对于脑呈高信号,在T2加权像上相对于脑呈低信号。这种表现与含黑色素肿瘤的手术及组织学发现相符。
