Ovarian thecoma is a benign and rare neoplasm that accounts for 0.5% to 1% of all ovarian tumors. A 55-year-old woman with known breast cancer underwent a metastatic workup before surgery. The 99mTc-MDP whole-body bone scan revealed intense uptake in the left pelvic region. Hybrid SPECT/CT imaging showed that the elevated 99mTc-MDP activity was in a tumor with calcification in the left adnexa. Dynamic enhanced MRI revealed marked enhancement of the tumor. Resection of the tumor was subsequently performed, and pathologic analysis confirmed the diagnosis of an ovarian thecoma.
