Coincidental Sphenoid Meningioma and Pituitary Adenoma: Case Report

ABSTRACT

We report a case of coincidental pituitary adenoma and sphenoid meningioma. Computed tomographic scan had shown a large intrasellar rim enhancing mass and another well-enhancing mass with reactive bony thickening on the medial sphenoidal ridge. Magnetic resonance image revealed a snow-man shaped, expansile intrasellar mass, with small supra-sellar component, and a small enplaque-type enhancing dural thickening on the right medial sphenoidal ridge. Histopathologically, the intrasellar mass was diagnosed as pituitary adenoma and the other mass as secretory meningioma. We present clinical, radiological, and histopathological findings and review the reported cases of coincidental pituitary adenoma and meningioma without irradiation or trauma.
