Fig1
Magnetic resonance imaging (MRI) of the brain confirmed inflammation and edema of the pituitary gland consistent with a diagnosis of hypophysitis (Fig. 1).
Fundus photos, taken after onset of right eye blurred vision, demonstrating mild swelling of the right optic disc (left) and pallor of the left optic disc (right)

Ophthalmologic examination was notable for visual acuity of 20/50 in the right eye with associated right eye decreased color vision, visual field constriction, and optic disc swelling; left eye vision remained no light perception (Fig. 2).
MRI orbits after onset of right eye vision loss, demonstrating subtle circumferential perineural enhancement of bilateral optic nerves, demonstrated on axial and coronal views consistent with optic nerve inflammation (highlighted by the arrows)

Fig3
MRI of the brain and orbits demonstrated circumferential enhancement of the right greater than left intraorbital optic nerves (highlighted by arrows) suggestive of optic neuritis (Fig. 3). MRA of the cerebrovascular system did not demonstrate any significant arterial stenoses.
