case_images: Pretreatment magnetic resonance imaging of our patient with endometriosis. Axial T1-weighted imaging at the first consultation. Two ovarian tumors (tumor size: right < left) show high-intensity signals (arrows), and the internal structure shows a blood-resistant component.

case_images: T1- and T2-weighted magnetic resonance images (MRI) revealed high-intensity signals in two ovarian tumors (tumor size: right < left) and masses with a maximum diameter of 59 mm in the left ovary (Figure 1).
case_images: Posttreatment magnetic resonance imaging of our patient with endometriosis. Axial T1-weighted imaging after seven years of treatment. The two tumors show high-intensity signals with a diameter of 35 mm or less (arrow), and the tumor size was a partial response.

case_images: MRI findings revealed high-intensity signals in two ovarian tumors with a diameter of 35 mm or less, and the tumor size indicated a partial response (Figure 2). Moreover, the level of tumor marker had decreased.
case_images: Posttreatment magnetic resonance imaging of our patient with endometriosis. MRI after eight years of treatment. The right ovary shows a mass with a maximum diameter of 114 mm (arrow). The solid part of the mass exhibits a low-intensity signal.

case_images: The solid part of the mass exhibited a low-intensity signal (Figure 3).
case_images: Posttreatment magnetic resonance imaging of our patient with endometriosis. PET/CT after eight years of treatment. Increased focal fludeoxyglucose accumulation (SUV max = 10.00) is observed in the solid elements of the right ovary (arrow).

case_images: PET/CT findings showed increased focal fludeoxyglucose accumulation (SUV max = 10.00) in the solid elements of the right ovary (Figure 4).
case_images: Pathological findings of the right ovary. Ovarian endometriosis of the right ovary. (H-E x20). Ectopic endometrial tissues exist in the cyst wall, and macrophages with hemosiderin are observed.

case_images: H&E staining displayed ovarian endometriosis and clear cell carcinoma of the right ovary (Figures 5 and 6).
case_images: Pathological findings of the right ovary: clear cell carcinoma of the right ovary (H-E x20) and proliferation infiltration of hobnail-like cells with pale eosinophilic cytoplasm.

case_images: fig6
case_images: H&E staining displayed ovarian endometriosis and clear cell carcinoma of the right ovary (Figures 5 and 6).
case_images: Clinical course of the patient. Increases in the level of the tumor markers, CA125 and CA19-9, are noted after six years of treatment. There was an observed decrease in the tumor markers following TC treatment.
