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.
Highlights
Paranasal sinus lymphoma is an uncommon malignancy which poses significant diagnostic challenges
Paranasal mass lesions can potentially cause visual loss by compressing the optic nerve, but only a few such cases have ever been reported in the literature [1,2,3,4,5]
The majority of head and neck NHLs originate from extranodular sites such as lymphoid tissue of Waldeyer’s tonsillar ring [7] whilst lymphomas of the nasal cavity and paranasal sinuses are rare, accounting for only 0.17% of all lymphomas [8]
Summary
Paranasal sinus lymphoma is an uncommon malignancy which poses significant diagnostic challenges. Paranasal mass lesions can potentially cause visual loss by compressing the optic nerve, but only a few such cases have ever been reported in the literature [1,2,3,4,5]
