title: Bilateral idiopathic inflammatory pseudotumor of the orbits.
abstract: Four cases of bilateral orbital idiopathic inflammatory pseudotumors are analysed as regards their clinical, CT and ultrasonographic features. Bilateral orbital involvement tends to occur in a younger age group while optic nerve involvement is invariable. Certain echographic features like variation of angle kappa, increase in the width of retrobulbar fat complex and decreased orbital pulsations on M-scan are highlighted.
