Rhabdomyosarcoma (RMS) is the most common paediatric soft-tissue sarcoma, making 50% of all diagnosed cases. It is a complex disease that has the potential to arise from any tissue of the body except the bones. There are four types of rhabdomyosarcoma; embryonal, botryoidal, alveolar and pleomorphic. [18F]-FDG PET-CT plays a vital role in staging, response evaluation and follow-up of the disease. Due to significant morbidity and mortality with high-risk disease, proper staging is of paramount importance. Staging of rhabdomyosarcoma depends on tumour localization, infiltration of local structures by the primary tumour, nodal involvement, and presence of visceral metastases. Without timely intervention, rhabdomyosarcoma progresses at an exponential speed. |
