Yolk sac tumor of the ovary: CT findings

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 n...

Description
Summary: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.
