ABSTRACT
INTRODUCTION: Incidentaloma is the result of the medical problem created by the development of imaging. Without a universal definition, incidentaloma describes any incidental finding revealed by a medical examination performed for another indication, and which will be the origin of a questioning intended to give it a clinical meaning. The frequency of incidentalomas is very variable depending on the imaging technique, the organ affected and the definition used. The aim of this study was to investigate the frequency of incidentalomas on computed tomography (CT) scans in a geriatric hospitalised population. METHODS: In an observational, retrospective, monocentric study, we analysed, for a full year, all the planned CT scans performed, during a hospitalisation in acute and subacute care service of a Parisian geriatric hospital in search of incidentalomas. RESULTS: 113 patients were included in the study, with a mean age of 87,4 years. The frequency of incidentalomas on CT scans in this population was 53 %, with an average of two incidentalomas per patient. Eight percent of the incidentalomas required further examination, specialist advice or treatment. We found incidentalomas in half of the brain and abdomino-pelvic CT scans and in a quarter of the chest CT scans. Age was not associated with the presence of incidentalomas. DISCUSSION: Incidentaloma has become an important part of current medical practice. The geriatrician must know how to anticipate it and propose to his patient an adapted management.
