Overview

CT scan is considered as one of the first steps for evaluation of rhabdomyosarcoma. Primary site CT scan, chest CT scan, abdominal and retroperitoneal CT scan are required for evaluation of rhabdomyosarcoma. On CT scan, rhabdomyosarcoma is characterized by soft tissue density, enhancement with contrast, and bone destruction.

CT

CT scan is considered as one of the first steps for evaluation of rhabdomyosarcoma.^[1]^[2]
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:^[3]
- Soft tissue density
- Enhancement with contrast
- Bone destruction
