Purpose:
To report spontaneous visual improvement in a patient with unilateral optic neuropathy due to pituitary metastasis.
Methods:
Report of a case.
Results:
A 54-year-old woman with a history of breast carcinoma lost vision in her right eye to 20/70 without any other symptoms. Six days later, vision spontaneously improved to 20/30. A pituitary mass compressing the right intracranial optic nerve was found on magnetic resonance imaging and the diagnosis of metastatic breast carcinoma was confirmed by biopsy.
Conclusions:
Spontaneous visual improvement can occur in the setting of compressive optic neuropathy by a solid mass.
