Extensive Metastases on 18F-FDG PET/CT in Primary Lymphoepithelioma-Like Carcinoma of the Ovary.
We describe extensive metastatic lesions of very rare lymphoepithelioma-like carcinoma originating from the ovary assessed by F-FDG PET/CT. A 59-year-old woman presented with abdominal distention. Pelvis MRI demonstrated a large right ovarian malignant lesion with massive lymphadenopathy suggesting lymphoma. Patient underwent surgical removal. The lymphoepithelioma-like carcinoma arising from the ovary based on immunohistochemistry was pathologically confirmed. Multiple metastases including peritoneum, omentum, and lymph nodes were confirmed. F-FDG PET/CT for staging and evaluation of metastasis after operation showed multiple lymph node metastases. F-FDG PET/CT revealed hepatic metastasis in the dome region of the right liver besides multiple skeletal metastases.
