The presence of two concomitant tumors in the sellar region, for example, pituitary adenoma and tuberculum sellae meningioma, is rare. Preoperative diagnosis and differentiation of these tumors are important because craniotomy is recommended for extirpation of meningioma. We present the case of a 52-year-old woman with visual field impairment. Magnetic resonance (MR) imaging revealed a sellar tumor (17×7×17 mm^3) with two intense signals after enhancement. It was resected and found to be pituitary adenoma and meningioma. The literature on the characteristics of these tumors in MR imaging and the approach options for their surgical resection is reviewed.
