| Abstract: | The aim of this study was to describe cross-sectional imaging features of recurrent papilloma of the nasal fossa and paranasal
sinuses and to evaluate the role of MR and CT in the postoperative follow-up of this lesion. Magnetic resonance imaging and
CT of ten patients who presented recurrence of inverted papilloma were reviewed and correlated to initial imaging, endoscopy,
and surgical reports. Imaging patterns of recurrent inverted papilloma are identical to those of initial tumors and recurrence
location is closely related to the site of the former lesion. Magnetic resonance is more efficient than CT for the diagnosis
and evaluation of extensions. Magnetic resonance supplies the deficiencies of endoscopy in case of extensions to the frontal
sinus or the lateral recess of the antrum, especially if mucosal hyperplasia or sinusitis is associated. Magnetic resonance
imaging is the first imaging modality to perform in the follow-up after removal of inverted papilloma.
