Coincidental Arteriovenous Malformation with Pituitary Tumor

ABSTRACT

Coincidental Arteriovenous malformation with pituitary tumor is very rare. Only two cases previously have been published in the world literature. A 63-year-old man was suffered from sudden loss of vision, vomiting and gait disturbance. Initial magnetic resonance image and cerebral angiography revealed a mass contained hemorrhage on pituitary fossa and arteriovenous malformation on the left frontal lobe. The tumor removed partially via transsphenoidal approach, and then embolization was performed for the arteriovenous malformation. Histological diagnosis of the mass was pituitary adenoma.
