Clear cell adenocarcinoma of the female urethra is a rare malignant tumor arising from urethral diverticulum or paraurethral ducts and glands, and extends to the submucosa surrounding the urethra. In the advanced stage, the tumor may involve adjacent organs such as the vagina, and may mimic gynecologic malignancy. We report 2 cases in which magnetic resonance imaging could reveal their urethral origin by detecting the normal urethra within the mass as targetlike appearance on axial T2-weighted image.
女性尿道透明细胞腺癌是一种罕见的恶性肿瘤，起源于尿道憩室或尿道旁管及腺体，并蔓延至尿道周围的黏膜下层。在晚期，肿瘤可能累及邻近器官，如阴道，可能类似妇科恶性肿瘤。我们报告2例，磁共振成像通过在轴位T2加权图像上检测肿块内正常尿道呈靶样表现，可揭示其尿道起源。
