Extraskeletal Tc-99m MDP uptake Accumulation in a calcified Uterine Leiomyoma: A benign mimic on Bone scan

Bone scintigraphy is primarily used for the assessment of osseous structures, soft tissue uptake of Tc-99m Methylenedeoxy- phosphonate (MDP) is unusual in normal circumstances and may lead to unsuspected diagnosis. We presenta case highlighting the importance of studying the soft tissues to assess for findings other than osseous on bonescintigraphy in a patient with prior history of breast carcinoma.Keywords: Breast cancer, calcified uterine fibroid, Tc-99m MDP bone scan
