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.

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).
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.

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.
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.

The solid part of the mass exhibited a low-intensity signal (Figure 3).
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).

PET/CT findings showed increased focal fludeoxyglucose accumulation (SUV max = 10.00) in the solid elements of the right ovary (Figure 4).
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.

H&E staining displayed ovarian endometriosis and clear cell carcinoma of the right ovary (Figures 5 and 6).
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.

H&E staining displayed ovarian endometriosis and clear cell carcinoma of the right ovary (Figures 5 and 6).
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.
