PET CT
The use of PET CT in initial
staging of skull base and temporal bone tumors should be tailored to
individual patients and their specific type of tumor. Full body PET CT
can be helpful in the preoperative staging of skull base and temporal
bone RMS including at initial diagnosis, during on therapy follow up for
patients with metastatic disease and during off therapy surveillance for
patients with metastatic disease. Such evaluation is similarly true for
the rare occurrence of other malignancies such as primary Ewing sarcoma
in the skull base and temporal bone. For the assessment of metabolic
response of rhabdomyosarcoma by FDG PET CT, it is still controversial
whether FDG PET CT can predict treatment
response38,39.
Further studies are needed to determine the role of PET CT in predicting
treatment response.
