The patient underwent a left canal wall-up tympanomastoidectomy, and the pathology report confirmed an inverted papilloma. Inverted papillomas are uncommon benign epithelial tumors related to a high recurrence rate and high risk of secondary malignant transformation after multiple surgeries. The patient has undergone 2 additional surgical interventions involving the neurosurgery team due to recurrent inverted papilloma that exerted a mass effect over the left cerebellar hemisphere. Despite no signs of recurrence on magnetic resonance imaging 5 years after the last surgery, at least 1 radiologic study per year is granted. Clinical multidisciplinary follow-up including nasal endoscopy and head and neck examination as a part of a stringent follow-up is essential to rule out synchronous nasosinusal inverted papillomas.\n\nCite this article as: Pe\u00f1aranda A, Pe\u00f1aranda D, P\u00e9rez-Herrera LC, Jim\u00e9nez-Hakim E.
