Abstract
A case of intracranial metastatic amelanotic melanoma with cyst is presented. The case is a 51-year-old female with malignant melanoma arising on her right chest. Two years after wide excision, skin and brain metastasis occurred. Brain MR images demonstrated a tumor with cyst in the left occipital lobe. And this metastatic melanoma was recognized as amelanotic melanoma, because the tumor showed low intensity on T1 weighted images and high intensity on T2 weighted images. There are only a few earlier reports of melanoma with cyst. Moreover, intracranial amelanotic melanoma is also very rare. [Skin cancer (Japan) 2002; 17: 182-188]
