RESUMO
INTRODUCTION: Incidental findings on comprehensive imaging in the adult trauma population occur at rates as high as 54.8%. We sought to determine the incidence of potentially malignant or pre-malignant incidental findings in a high-volume level 1 trauma center and to evaluate follow-up recommendations. METHODS: This was a retrospective review of all patients with incidental findings on imaging who were admitted to the trauma service at our level 1 trauma center between January 1st, 2014, and October 1st, 2019. A multi-disciplinary team characterized findings as potentially malignant or pre-malignant. RESULTS: The study included 495 patients who had incidental findings, 410 of whom had potentially malignant or pre-malignant findings on imaging, resulting in a cumulative incidence of 6.6%. The mean age was 65 and 217 (52.9%) patients were male. The majority of "incidentalomas" were discovered on CT imaging (n=665, 98.1%); over half were solid (n=349, 51.5%), while 27.4% were cystic (n=186) in nature. The lungs (n=199, 29.4%), kidneys (n=154, 22.8%), liver (n=74, 10.9%), thyroid gland (n=58, 8.6%), and adrenal glands (n=53, 7.8%) harbored the most incidentalomas. Less than half of patients with incidental findings received specific follow-up recommendations on the radiologist's report (n=150, 39%). Sixty-one percent of patients (n=250) had their incidentalomas detailed in the discharge paperwork. CONCLUSION: The results of our study suggest that potentially malignant or pre-malignant incidental findings are common among trauma patients. Specific follow-up recommendations were not presented in 61% of the radiology reports, highlighting the need to standardize medical record capture of an incidentaloma to ensure adequate and appropriate follow-up.
