Orbital pseudotumours clinical, radiographic and histopathologic features in 30 cases with a review of the literature

ABSTRACT

This retrograde study included 30 cases of orbital pseudotumors seen in the last 10 years in Tanta University Ophthalmic Hospital. Proptosis, diplopia, and pain were the main clinical features. CT scan was very helful in differentiating seudotumours from other infiltrative orbital mass lesions. Histopathologically, pseudotumours may be either a chronic non-specific inflammatory pattern or a pseudolymphoma pattern. The results of surgical interference were very unsatisfactory where as the response of the lesions to sterois for long periods was excellent
