Unilateral ovarian metastasis from gastric mucinous adenocarcinoma visualized on FDG PET/CT

摘要

BACKGROUND: Krukenberg tumor is a metastatic ovarian tumor with primary focus usually seen in the gastrointestinal tract. Metastatic involvement of the ovary is an uncommon manifestation of malignancy. We report a [18F]-fluoro-2-deoxy-D-glucose positron-emission tomography/computed tomography (FDG PET/CT) appearance of solitary unilateral ovarian metastasis in a 44-year-old woman with a history of mucinous adenocarcinoma type of gastric carcinoma. Total hysterectomy with bilateral salpingo-oophorectomy was performed. Histopathological verification determined metastasis of mucinous adenocarcinoma with components of signet-ring cell carcinoma in the right ovary.
