Orbital lymphangioma: An analysis of 26 patients

Abstract

Aim. To evaluate retrospective data on the clinical findings, histological features, radiological diagnosis, and management outcomes in orbital lymphangioma. Methods. Data on 26 orbital lymphangioma patients managed over 16 years were re-evaluated. The computed tomograph and magnetic resonance scans and histological slides were reviewed. Parametric techniques were used to assess correlations among clinical, radiological, and histopathological factors. Results. At presentation proptosis was present in 85%, ptosis in 73%, and restrictive eye movements in 46% of patients. The accuracy of the initial radiology interpretations was 77%. 24 cases required one or more surgeries. The mean follow up was 9.2 years (range 1-14 years). 58% of patients developed recurrences. In cases that recurred, motility restriction was significantly more frequent at initial examination than cases without recurrence (p < 0.05). After therapy, 75% of patients were satisfied with their visual function and cosmetic appearance. Conclusions. Conservative management of orbital lymphangioma with multiple partial resections may achieve satisfactory results.
