Incidental Ovarian Uptake in Bone Scintigraphy

A 47-year-old woman, recently diagnosed with breast cancer, underwent staging. A whole-body bone scan revealed an unexpected focal 99m Tc-MDP uptake in her right ovary. Extensive literature review suggested various malignant pathologies for this incidental ovarian uptake. Despite inconclusive results from other imaging modalities, the multidisciplinary tumor board recommended right ovarian resection due to a history of abnormal uterine bleeding. The final pathology confirmed an adult-type granulosa cell tumor. Interestingly, subsequent surgery performed for staging purposes found no additional tumor sources. This case highlights the enhanced diagnostic value of hybrid imaging in bone scintigraphy.
