ORBITAL PSEUDOTUMOR POSSIBLY DUE TO SARCO IDOSIS

Background. - Orbital inflammatory lesions may be due to infection, ne oplasia, systemic disease such as sarcoidosis or be idiopathic. Case r eport. - A 13 year-old boy had uveitis and symptoms of unilateral peri globular orbital inflammation, confirmed by computed tomography. Infec tion and neoplasia were excluded. The serum angiotensin-converting enz yme level (ACE) was normal. Steroids were effective bur three recurren ces occurred with bilateralisation of the lesion. Serum ACE level incr eased making sarcoidosis probable, Moreover renal lesion were later fo und. Outcome was good with a prolonged steroid administration for ten months. Conclusions. - Sarcoidosis may be revealed by an orbital infla mmatory lesion. Steroids are necessary to prevent ocular functional co mplications.
