RESUMEN
PURPOSE: To describe the clinical manifestations, radiologic findings, and treatment outcomes of pediatric pseudotumors. METHODS: A retrospective chart review of patients diagnosed with pediatric pseudotumor (age under 20 years old) from August 2008 to February 2012 was performed. RESULTS: Thirteen patients (16 eyes) were included in this study. The mean age of the subjects was 14.2 years (5-20 years). Swollen eyelid (56.3%), ptosis (43.8%), conjunctival injection (18.8%), localized mass (18.8%), limitation of ocular movement (12.5%), proptosis (6.3%), and decreased visual acuity (6.3%) were found initially. Dacryoadenitis (62.5%), myositis (18.8%), anterior orbital inflammation (18.8%), and diffuse type (6.3%) were observed on orbital computed tomography (CT). Among the 13 patients (16 eyes), 8 patients (10 eyes) were administered oral systemic corticosteroids, 2 patients (2 eyes) received IV systemic corticosteroid, 1 patient (1 eye) received systemic corticosteroids combined with NSAID, and 2 patients (3 eyes) were prescribed NSAIDs only. Symptoms improved 4.1 days after initiation of treatment. CT scans revealed that one patient experienced diffuse-type disease recurrence twice. CONCLUSIONS: Orbital pseudotumors, which are rare in younger people, are likely to respond very well to corticosteroid treatment, and the recurrence of orbital inflammation is rare.
