Orbital pseudotumor as a presenting sign of temporal arteritis.

Both unilateral proptosis (2 cases) and radiological evidence of orbital inflammatory pseudotumor in the absence of exophthalmos (1 case) have been separately described as presenting signs of temporal arteritis. We report a patient presenting with bilateral exophthalmos associated with CT and MRI signs of orbital inflammation, who had biopsy-proven temporal arteritis. Our case is unique in view of the association of the above clinical and radiological features, and the bilateral involvement of orbital tissues.
