Compressive Optic Neuropathy Caused by Orbital Non-Hodgkin's Lymphoma

Abstract

Purpose . To present a unique case of Non-Hodgkin’s-Lymphoma- (NHL) associated compressive optic neuropathy. Method . An 89-year-old male presenting with acute unilateral visual loss and headache. Results . Patient was initially diagnosed with occult giant cell arteritis; however after visual acuity deteriorated despite normal inflammatory markers, an urgent MRI scan revealed an extensive paranasal sinus mass compressing the optic nerve. Conclusion . Paranasal sinus malignancies occasionally present to the ophthalmologist with signs of optic nerve compression and must be included in the differential diagnosis of acute visual loss.
