title: Sinonasal inverted papilloma mimicking a pituitary macroadenoma.
abstract: We report the rare entity of an inverted papilloma arising from the sphenoid sinus that we expected to be a pituitary tumour on the basis of history, examination and pre-operative investigations, especially MRI appearance. Inverted sinonasal papilloma should be considered in the differential diagnosis of pituitary macroadenoma invading the sphenoid sinus.
