摘要：
As a follow-up to a case previously reported, a rare case of malignant transformation of cellular blue nevus (CBN) in the central nervous system preoperatively diagnosed by magnetic resonance imaging (MRI) is reported. On MRI, the malignant portion of the nevus was slightly hyperintense on both T1- and T2-weighted images. In contrast, the benign portion with a great deal of melanin was hyperintense on T1-weighted image and hypointense on T2-weighted image. MRI was useful and indispensable for detecting the malignant transformation of CBN.
