Bilateral retrobulbar neuritis in an adolescent boy with lymphoma

A 13-year-old boy presented with bilateral retrobulbar neuritis. Three months later he presented with unilateral proptosis and cervical lymphadenopathy. Lymph node biopsy confirmed non-Hodgkin's lymphoma, B-cell type. To the best of our knowledge, this is the first reported case of bilateral retrobulbar neuritis as the presumptive initial presentation of non-Hodgkin's lymphoma.
