Figure 1

(a) Abdominal plain computed tomography (current). A huge mass measuring 21 cm in longest diameter can be seen in the right cranial portion of the uterine body. The mass is partially solid, suggesting malignancy. (b) Abdominal plain computed tomography (image obtained 10 years prior to the current admission). A mature cystic teratoma measuring 6 cm in diameter is observed on the right side. There are no findings suggestive of malignancy, such as a mural nodule or a solid component.
