We discussed a rare case of [99mTc]Tc-Methylene diphosphonate (MDP) uptake in the malignant ovarian tumor of a post-menopausal woman. She was referred for bone scintigraphy following the diagnosis of high-grade papillary serous adenocarcinoma of the ovary, which was identified after the detection of a Sister Mary Joseph's node during umbilical herniorrhaphy surgery. The whole body bone scan and post-void static images demonstrated a smeared area of persistent [99mTc]Tc -MDP uptake in the right pelvic region, adjacent to the bladder. Subsequent SPECT/CT imaging, prompted by lumbar pain, localized the uptake to the dystrophic calcification within the ovarian tumor. This case underscores the importance of paying attention to extra-osseous MDP uptake, such as within the ovary and uterine adnexa, as it can provide valuable diagnostic clues for further evaluation and increase the likelihood of identifying previously undetected pathologies.
