DOI: 10.1590/S0004-27302011000100013

The objective of this study is to report and discuss a rare and inflammatory cause of exophthalmos. This report describes a patient with exophthalmos, who was initially diagnosed with euthyroid Graves’ with good response to therapy. After 8 years of follow-up, she had recurrence of symptoms and a new evaluation revealed the final diagnosis of orbital pseudotumor. Orbital pseudotumor is an uncommon disorder that both radiologically and clinically mimics a malignant process or other inflammatory disease, such as Graves’ ophthalmopathy.
