Coexistent pituitary adenoma and frontal convexity meningioma with frontal sinus invasion: A rare association

The coexistence of pituitary adenoma (PA) and meningioma in the same patient is rare, after excluding radiotherapy-induced meningiomas. Most of the literature on their coexistence describes meningiomas located in the close vicinity to PA, that is, in the sellar/parasellar region. We describe a case of a 65-year-old lady with a nonfunctioning PA and an associated frontal convexity meningioma with frontal sinus invasion. The imaging was nonspecific for the meningioma, and its association with concomitant PA has not been reported before.
