title: Computed tomographic features in optic neuritis.
abstract: A computed tomography scan obtained in two patients with monocular visual loss showed diffuse enlargement and enhancement of the intraorbital portion of the involved optic nerve. Although these tomographic features were initially interpreted as an optic nerve glioma by the neuroradiologist, the ensuing clinical course established the diagnosis of optic neuritis.
