title: Imaging features of primary and secondary adult rhabdomyosarcoma.
abstract: OBJECTIVE
  Rhabdomyosarcomas are rare and aggressive soft-tissue sarcomas in adults. The purpose of this article is to describe the imaging features of primary and secondary adult rhabdomyosarcomas utilizing MRI, CT, and (18)F-FDG PET/CT.
  
  
  CONCLUSIONS
  MRI is the imaging technique of choice for the evaluation of primary rhabdomyosarcoma involving most body sites (extremity, pelvis, head, and neck), with the added advantages of diffusion-weighted imaging and whole-body MRI for staging. CT and FDG PET/CT play major roles in the evaluation of metastatic disease. Because the imaging features of adult rhabdomyosarcoma are nonspecific, other parameters, such as clinical findings, age, site, lymphadenopathy, and metastatic disease, should be combined to narrow the differential diagnosis.
