A 75-year-old woman with radiation-induced vitreous hemorrhage after proton-beam radiotherapy for choroidal melanoma of the left eye. The patient underwent secondary enucleation one year after radiotherapy because of painful eye. Axial (a) T2-weighted FLAIR (from brain MRI scan), b fat-suppressed T1-weighted, c T2-weighted turbo spin-echo and (d) DW (b = 1000 s/mm2) images. The anterior chamber and the vitreous body of the left eye demonstrate inhomogeneous high signal intensity on T2-weighted FLAIR and T1-weighted images (white asterisks). On T2-weighted image, an intraocular fluid–fluid level, with relative hypointensity of the declivous portion (white asterisk), is recognizable within the left globe. Note the difference with the physiological water-like signal intensity of the contralateral eye. On DW image, the left vitreous body exhibits restricted diffusion with high signal intensity (black asterisk). The findings are consistent with extensive vitreous hemorrhage. A dome-shaped intraocular lesion (white arrows in a and c) is recognizable along the lateral aspect of the left globe
