膀胱原發性惡性黑色素瘤在磁振造影上之表現:一個罕見的病例報告

摘要


本文報告一罕見之膀胱原發性惡性黑色素瘤病例在磁振造影上之表現。病灶在以T1及T2為主影像中均表現為稍高之訊號強度,並有很好的周邊性顯影。與組織切片下低度黑色素含量之發現吻合。

We report a case of primary malignant melanoma of the urinary bladder with MR imaging. The lesion was moderately hyperintense on both T1- and T2-weighted images with good peripheral enhancement, which might be compatible with the intermediate melanin contents (less than 10% melanin-containing cells) on the histologic findings.
