A rare case of intracranial metastatic amelanotic melanoma with cyst is presented. The patient was a 51 year old woman with a malignant melanoma arising on her right chest. Two years after a wide excision, skin and brain metastasis occurred. Brain magnetic resonance images demonstrated a tumour with a cyst in the left occipital lobe. Because the tumour showed low intensity on T1 weighted images and high intensity on T2 weighted images, the metastatic melanoma was identified as an amelanotic melanoma. Intracranial amelanotic melanoma is very rare, and there have been few reports of melanoma with cyst.
本文报告1例罕见的伴有囊肿的颅内转移性无色素性黑色素瘤。患者为51岁女性，右胸出现恶性黑色素瘤。广泛切除术后两年，发生皮肤和脑转移。脑部磁共振成像显示左枕叶有一个带囊肿的肿瘤。由于该肿瘤在T1加权图像上呈低信号，在T2加权图像上呈高信号，转移性黑色素瘤被确诊为无色素性黑色素瘤。颅内无色素性黑色素瘤非常罕见，关于伴有囊肿的黑色素瘤的报道很少。
