An 18F-FDG PET/CT showed high 18F-FDG uptake in a tumor in the pouch of Douglas, in 3 lymph nodes in the pelvis, and in the left tuber ischiadicum. Biopsies revealed a mesonephric carcinoma with metastases. Six series of empiric chemotherapy with carboplatin, paclitaxel, and bevacizumab were not sufficient to treat the cancer, and checkpoint immunotherapy with nivolumab and ipilimumab was initialized.
