Fig. 17. Male primary lung adenocarcinoma patient presenting with left sided blindness.

Axial T2W (A) and axial T1W (B) post gadolinium images from orbital MRI study show T2W hypointense intraocular lesions arising adjacent to sclera in left medial globe and close to left optic nerve head. Medial lesion shows contrast enhancement. Considerations include metastases (highly likely given clinical history) with amelanocytic melanoma (no T1W hypointensity; images not shown), less likely differential. No choroidal detachment is detected. T1W = T1-weighted, T2W = T2-weighted
