Overview
CT
On CT scan, rhabdosarocma is characterized by:
- Soft tissue density.
- Some enhancement with contrast.
- Adjacent bony destruction seen in over 20% of cases.
Rhabdomyosarcoma of biliary tract
- CT may show a heterogenous or hypo-attenuating mass with biliary ductal dilatation.
Rhabdomyosarcoma of the orbit
- Rhabdomyosarcomas are typically homogeneous soft tissue masses isodense to normal muscle.
- The mass may extend into the eyelid or through bone into the paranasal sinuses (especially the ethmoid sinus) and superiorly into the anterior cranial fossa.
Cardiac rhabdomyosarcoma
- CT may show a smooth or irregular low-attenuation mass in a cardiac chamber.
