[Invasive sinonasal papilloma with intracranial invasion: Case report and bibliographic review].

Introduction: Inverted papilloma is a locally-aggressive benign neoplasm of the paranasal sinuses with a high potential for recurrence and malignancy. Intracranial extension is infrequent, and dural penetration even more so, typically associated with recurrence of the disease or its degeneration into squamous cell carcinoma.

Clinical Case: A 32-year-old female patient consulted us for an exophytic lesion in her right nostril and exophthalmos, associated with headache, anosmia and dysgeusia.
