The purpose of this study is to determine the incidence and significance of incidental findings on pediatric oncologic PET/CT. A retrospective analysis of all PET/CT scans obtained at Helen DeVos Children’s Hospital between 2004-2008 in pediatric oncology patients was performed.Specific data points for study including DOB, primary diagnosis, secondary diagnosis, treatment status (chemotherapy and radiation) and PET/CT findings were obtained. Studies were reviewed and findings confirmed with board certified Nuclear Medicine and Pediatric Radiologists. Total of 104 patients with various tumors/malignancies underwent 323 integrated PET/CT for staging or monitoring. Of these 104 patients, 71 (68%) had at least one incidental finding present on the PET/CT and 116 of 323 (36%) studies had at least 1 incidental CT finding. In conclusion, our retrospective study shows that careful evaluation of especially the CT component of integrated PET/CT scans provides clinically important information which may necessitate additional workup or treatment.
