Metastatic ovarian carcinoma showing surprisingly widespread subcutaneous 99mTc-MDP soft-tissue uptake

Skin Uptake of 99mTc-HDP in a Case of Annular Elastolytic Giant Cell Granuloma

Sometimes unexpected extraosseous uptakes appear in a bone scintigraphy as a consequence of a wide spectrum of nonosseous disorders. Recognition of these findings is important to enhance the diagnostic value of bone scintigraphy. We report a case of intense bone scintigraphy cutaneous uptake due to elastolytic actinic giant cell granuloma (EAGCG). We present the case of a patient with intense extraosseous uptakes of Tc-HDP that appeared in a bone scintigraphy that was performed for lumbar pain.

A large pelvic soft tissue mass implied by subtle bone scan findings

An 18-year-old man with alveolar rhabdomyosarcoma and osseous metastases underwent bone scintigraphy to monitor the effect of chemotherapy. The images showed significant improvement of bone lesions. However, the scan revealed a vertically shaped urinary bladder and diffused increased activity in the genital region. A diagnostic pelvic CT was subsequently performed, which showed a thickened bladder wall, an ill-defined pelvic mass, and extensive subcutaneous edema in the genital region.
