A rare case of testicular embryonal rhabdomyosarcoma detected incidentally on bone scan

The role of nuclear medicine diagnostic bone scanning is well established, and the potential for detecting incidental findings is well-known. This case provides an insight into the specific role bone scanning plays in unraveling a complex clinical case. Furthermore, it highlights the importance of single-photon emission computed tomography in differentiating benign from malignant findings, particularly when subtle. The case is an excellent example of a rare disease (adult testicular embryonal rhabdomyosarcoma) requiring correlative imaging and histology for diagnosis.
