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 Methylene deoxy- phosphonate (MDP) is unusual in normal circumstances and may lead to unsuspected diagnosis. We present a case highlighting the importance of studying the soft tissues to assess for findings other than osseous on bone scintigraphy in a patient with prior history of breast carcinoma.
