case_images: Images (A, B) (taken on 2022-12-14) reveal a large solid-cystic mass occupying the lower abdomen and pelvic cavity, which contained scattered punctate calcifications and shadows with fat density; image (C) (taken on 2023-11-27) demonstrates multiple masses in the pelvic and abdominal cavities fused into a huge irregular continuous mass.

case_images: Multiple nodular shadows were observed in the peritoneum and greater omentum ( Figures 1A, B ). Preoperative CT results showed multiple masses in the pelvic and abdominal cavities fused into a huge irregular continuous mass ( Figure 1C ).
case_images: Representative histology of immature and mature teratoma. In image (A) (HE x100), the resected specimen of original ovarian immature teratoma showing primitive neural tube. Mature teratoma after chemotherapy in the same patient composed of various tissue components such as fat and cartilage (image B, HE x100), as well as neuroglia and intestinal epithelium (image C, HE x40).

case_images: Histopathological analysis of the mass and omentum revealed a stage IIIc high-grade immature teratoma (grade 3), with abundant immature intestinal epithelium present within the tumor, and no distinct yolk sac tumor components were identified ( Figure 2A ). No immature components were detected ( Figures 2B, C ).
case_images: Images (A, B) (taken on 2023-07-19) indicate multiple masses in the pelvic and abdominal, with the largest located in the hepatogastric space; images (C, D) (taken on 2023-09-24) show an enlargement of the pelvic and abdominal masses.
