Plain CT and contrast-enhanced CT revealed a large solid mass with cystic areas (Figures 1(a) and 1(b)).
(a) T1-weighted magnetic resonance imaging depicting a mass in the right adnexal region with high signal intensity relative to that of the myometrium. (b) On T2-weighted imaging, the solid component of the mass exhibited slightly low signal intensity, and the large cystic component exhibited high signal intensity. (c) Diffusion-weighted imaging depicting a mass with high signal intensity relative to that of the endometrium. (d) On precontrast fat-saturated T1-weighted imaging, the mass exhibited slightly high signal intensity. (e) On early-phase contrast-enhanced fat-saturated T1-weighted imaging, the mass exhibited strong high signal intensity. (f) On delay-phase contrast-enhanced fat-saturated T1-weighted imaging, the mass exhibited slightly high signal intensity.

T1-weighted MRI depicted a mass in the right adnexal region with high signal intensity relative to that of the myometrium (Figure 2(a)). On T2-weighted MRI, the solid component of the mass exhibited low signal that contained small areas of hyperintensity, and the signal intensity of the large cystic component was high (Figure 2(b)). Diffusion-weighted imaging depicted high signal intensity relative to that of the endometrium (Figure 2(c)). In precontrast fat-saturated T1-weighted imaging, the mass exhibited slightly high signal intensity (Figure 2(d)). On early-phase contrast-enhanced fat-saturated T1-weighted imaging, the mass exhibited marked high signal intensity (Figure 2(e)). T1-weighted imaging, the mass exhibited slightly high signal intensity (Figure 2(f)). The preoperative diagnosis was endometrioma with related malignant tumor, such as clear cell carcinoma or endometrioid carcinoma.
(a) A surgical specimen from right adnexectomy of a 12 x 9 x 7 cm mass revealed a yellowish-white cut surface, a smooth internal surface, and an almost solid component. (b) Microscopy examination revealed multiple small or microcystic spaces that contained mucinous fluid or hemorrhage and ovarian stromal intervening fibrous tissues and multiple vascular spaces. (c) Microscopic examination of the papillary-structured architecture revealed mucus-producing tumor cells with moderate atypia.

The surgical specimen from right adnexectomy consisted of a 12 x 9 x 7 cm mass with a yellowish-white cut surface, a cystic component containing dark yellow fluid, a smooth internal surface, and an almost solid component (Figure 3(a)). Microscopy examination revealed multiple small cystic spaces that contained mucinous fluid or hemorrhage and ovarian stromal intervening fibrous tissues and multiple vascular spaces(Figure 3(b)). Mucus-producing tumor cells with moderate atypia were detected in the papillary-structured architecture. (Figure 3(c)).
