Splenic and multiple abdominal metastases of endometrial carcinoma detected with FDG-PET/CT.

A 58 year old female was referred for FDG-PET/CT for restaging of endometrial adenocarcinoma. For evaluation of treatment, no metastases were detected on FDG-PET/CT which was performed 18 months later after the surgery. During follow-up, FDG-PET/CT was performed 6 months later than the previous FDG-PET/CT for restaging. A lesion with increased metabolic activity (SUV max: 10.21) was detected at spleen which was not seen on previous FDG-PET/CT scan. The lesion was consistent with metastasis of endometrial carcinoma. Splenic metastasis of endometrial carcinoma is extremely rare. There are only 13 cases of splenic metastasis from endometrial carcinoma that reported in the literature before. There is only one splenic metastasis of endometrial carcinoma case reported in the literature which is imaged with FDG-PET. To best of our knowledge this is the first report of solitary splenic metastasis of endometrial carcinoma that is imaged with FDG-PET/CT.
