Suprasellar Meningioma With Intrasellar Extension Simulating Pituitary Adenoma

To the Editor. —Recently, we treated a case of suprasellar meningioma with intrasellar extension that simulated pituitary adenoma. Report of a Case. —A 69-year-old diabetic woman noted progressive visual loss in the right eye over a nine-month period and the recent onset of visual dysfunction on the left side. On neuro-ophthalmic examination, visual acuity was 10/200 OD and 20/50 OS, with marked bilateral color vision abnormalities. A right afferent pupil defect was detected and a visual field examination (Goldmann) disclosed bitemporal hemianopia (Fig 1). The right optic nerve head had minimal diffuse pallor, but no defect in the nerve fiber layer was observed. Computed tomography of the sellar area (Fig 2) revealed the presence of a large intrasellar and suprasellar mass with homogeneous enhancement after the administration of intravenous contrast medium. Serum prolactin and thyroid hormone levels were normal. A tentative diagnosis of nonsecreting pituitary adenoma was made and a
