A 40-year-old woman with ovarian cancer (papillary adenocarcinoma) after surgery and chemotherapy for 2 years, who was referred for routine follow-up. The whole-body scan (a, anterior; b, posterior) revealed a single focus of high 99mTc-MDP activity in the left pubic bone region (black arrow). Axial CT (c), and SPECT/ CT images (d) showed that the elevated 99mTc-MDP activity was located in a left inguinal lymph node with calcification (white arrow). Resection of the lymph node was performed and pathologic analysis confirmed the diagnosis of lymph node metastases
