On CT scan, rhabdomyosarcoma is characterized by soft tissue density, enhancement with contrast, and adjacent bone destruction.

CT scan is considered as one of the first steps for evaluation of rhabdomyosarcoma.^[1]
The following CT scans are required in rhabdomyosarcoma:
- Primary site CT scan
  - For assessment of bone erosion and nearby lymph node involvement
  - For assessment of patient's response to treatment
- Chest CT scan
  - For evaluation of metastatic lesions
- Abdomen and retroperitoneal CT scan (thin-cut 5 mm sections)
  - For assessment of retroperitoneal nodal involvement in paratesticular rhabdomyosarcoma
Possible CT scan findings of rhabdomyosarcoma are:^[2]
- Soft tissue density
- Enhancement with contrast
- Bone destruction
