Use of computerized axial tomography (CAT scan) in evaluating therapy of orbital pseudotumor.
Two patients with orbital pseudotumor, demonstrated by computerized axial tomography (CAT scan), are presented. This radiological technique was further used to demonstrate the complete resolution (Case 1) and marked regression (Case 2) of the orbital masses after steroid therapy. CAT scan characteristics of orbital pseudotumor were discussed and contrasted with the findings in thyroid ophthalmopathy. It is our recommendation that patients with CAT scan and clinical characteristics of orbital pseudotumor should be treated with systemic steroids and resolution of the inflammatory lesion should be corroborated by a repeat scan in atypical cases. Orbital surgery and other invasive studies should be used in those patients in whom there is no objective improvement in the disease process.
