18F-FDG PET/CT Findings of an Isolated Splenic Metastasis From Endometrial Adenocarcinoma

Abstract

Splenic metastasis from endometrial carcinoma is rare, especially when the spleen is the sole metastatic site. Herein, we report the case of a 47-year-old woman with a history of endometrial adenocarcinoma diagnosed 1 year ago. At that time, she underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic node dissection. Restaging ¹⁸ F-FDG PET/CT demonstrated an isolated splenic mass with elevated FDG activity. There were no other signs of recurrence. The lesion was surgically resected and diagnosed as a metastasis from the endometrial adenocarcinoma.
