背景：本研究的目的是评价经病理证实的卵巢卵黄囊肿瘤的CT表现。方法：两名放射科医师对10例卵黄囊肿瘤的CT表现进行回顾性评价。亮点标志的存在；一侧;坏死的存在；分析了肿块的大小、边缘和形状。结果：患者平均年龄22岁（11 ~ 34岁）。肿瘤平均大小为14cm （11.1 ~ 18.5 cm）。10例肿瘤CT后均表现为亮点征，部分坏死，边缘光滑。所有肿瘤均为单侧。10个肿瘤中有9个呈椭圆形。结论：卵巢卵黄囊肿瘤CT表现为单侧光滑边缘大肿块，伴亮点征，部分坏死。
Background: The purpose of this study was to evaluate computed tomographic (CT) findings of pathologically proven yolk sac tumors of the ovary.Methods: Two radiologists retrospectively evaluated CT findings of 10 yolk sac tumors in consensus. The presence of bright dot sign; laterality; presence of necrosis; size, margin, and shape of the mass were analyzed.Results: Mean age of patients was 22 years ( ranging from 11 to 34 years). Mean size of the tumors was 14 cm ( ranging from 11.1 to 18.5 cm). All 10 tumors showed bright dot sign, necrotic portion, and smooth margin in post-contrast CT scan. All the tumors were unilateral. Nine of 10 tumors showed oval shape.Conclusions: On CT scans, ovarian yolk sac tumors appeared as large, unilateral, smooth marginated mass with bright dot sign and necrotic portion.
