Multimodal imaging of secondary vitreoretinal lymphoma with optic neuritis and retinal vasculitis

PURPOSE: To report the findings determined by multimodal imaging in an eye with secondary vitreoretinal lymphoma (VRL) with optic neuritis and retinal vasculitis. OBSERVATION: The case was a 71-year-old woman with a secondary VRL exhibiting optic neuritis and retinal vasculitis in her right eye. Color fundus photographs and fluorescein angiograms showed optic neuritis and vasculitis in the posterior pole of the right eye. Indocyanine green angiography showed dye staining of the retinal vein walls in the late phase. Fundus autofluorescence showed fuzzy hyper-autofluorescence surrounded by mottled hyper-and hypo-autofluorescence in the right eye. OCT showed a retina with uniform infiltration and a thickened retinal pigmented epithelium (RPE) layer, perforated RPE, small RPE detachments, and hyperrefrective or isorefrective masses on the degenerated RPE layer in the marginal area. Her left eye showed a degenerated RPE and oval shaped iso-reflective lesions on the RPE. CONCLUSION: The findings indicate that it is important to examine the marginal areas of eyes clinically diagnosed with VRL accompanied by optic neuritis and retinal vasculitis by multimodal imaging because these images can show the inflammatory signs of typical VRL including the sub-RPE lesions.
