Imaging of pelvic rhabdomyosarcoma by bone scintigraphy

Urinary tract distortion caused by pelvic rhabdomyosarcoma was imaged during 99mTc-oxidronate bone scintigraphy for suspected metastatic disease. This appearance correlated well with the anatomy defined on other imaging modalities. Bone scanning also proved valuable in detecting an otherwise occult osseous metastasis from this unusual tumor.
