Idiopathic Orbital Pseudotumor Preceding Systemic Inflammatory Disease in Children.

PURPOSE: To describe four pediatric cases in which isolated orbital pseudotumor preceded the development of a systemic inflammatory disease by months to years.

METHODS

The medical records of all patients with the clinical diagnosis of orbital pseudotumor seen at the Ocular Oncology Service of Wills Eye Hospital and Northern Virginia Ophthalmology Associates from 2010 to 2015 were reviewed retrospectively, and those associated with systemic inflammatory disease were selected for further study. Data were retrospectively collected from medical record review regarding patient demographics and clinical features, time to development of systemic inflammatory disease, and medical management.

RESULTS

In four pediatric patients, isolated orbital pseudotumor preceded the development of a systemic inflammatory disease, including pauciarticular juvenile idiopathic arthritis, eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome), granulomatosis with polyangiitis (Wegener's granulomatosis), and Crohn's disease.

CONCLUSIONS

Orbital pseudotumor may be an antecedent to systemic inflammatory disease in children. Because this was a small case series, the authors are not ready to suggest that a full systemic work-up for systemic inflammatory disease is warranted for every patient with orbital pseudotumor. However, close observation and suspicion for systemic inflammatory conditions may be reasonable in children who present with idiopathic orbital pseudotumor.
