    Author: Pushker N, Meel R, Bajaj MS, Kashyap S, Khuriajam N, Gupta S, Chandra M.
    Journal: Ophthalmic Plast Reconstr Surg; 2009; 25(6):450-4. PubMed ID: 19935247.
    Abstract:
    PURPOSE: To report a series of 7 cases of orbital abscess with unusual features that may mimic other cystic orbital lesions. METHODS: Retrospective study of all cases of orbital cellulitis/abscess treated at our center, over 1 year, highlighting cases with unusual features. RESULTS: Thirty-one cases were studied, where orbital cellulitis/abscess was the final diagnosis. Of these, 7 patients did not have typical signs and/or symptoms of local infection. At presentation, there was no associated predisposing risk factor, indicating the source of infection. The duration of symptoms, among these 7 patients, ranged from 3 weeks to 6 months. The initial diagnosis was myocysticercosis in 3 cases, orbital dermoid in 1 case, lymphangioma in 1 case, pseudotumor in 1 case, and schwannoma in 1 case. CONCLUSIONS: Unusual presentations of orbital abscess can mimic other conditions of the orbit. Orbital abscess should be considered in the differential diagnosis if a cystic lesion has not responded or partly responded to systemic antibiotics and there are associated signs or symptoms of intermittent or constant low-grade inflammation, even in the absence of predisposing risk factors.
