title: Recurrent ovarian carcinoma presenting as a solitary sternal metastasis on FDG PET/CT.
abstract: We report the positron emission tomography/computed tomography appearance of solitary sternal metastasis from primary ovarian carcinoma in a 65-year-old woman who underwent surgery followed by chemoradiation treatment 3 years earlier. Restaging positron emission tomography/computed tomography study demonstrates an intensely active destructive lesion involving the entire sternum (maximum standard uptake value: 4.7) with a photopenic soft tissue mass component in the center of the sternum protruding anteriorly suggestive of necrosis. This sternal lesion was subsequently biopsied and pathology revealed metastatic disease from the primary ovarian tumor for which the patient had received chemoradiation therapy. Bone involvement in ovarian cancer is relatively rare and even rarer in the sternum.
