A 54-year-old man with a poorly pigmented choroidal melanoma and hemorrhagic retinal detachment of the right eye. (a, b) Axial fat-suppressed T1-weighted images demonstrate a dome-shaped intraocular mass along the postero-lateral aspect of globe (white arrow in a), displaying intermediate signal intensity because of low melanin content. A hemorrhagic retinal detachment, exhibiting the typical biconvex lentiform shape, is appreciable along the posterior aspect of globe (white arrowheads in b) and on both sides of the lesion (white arrowheads in a); the retinal detachment shows high signal intensity because of subacute hemorrhagic content. On (c, d) axial contrast-enhanced fat-suppressed T1-weighted images the choroidal melanoma exhibits vivid enhancement (white arrow in c), whereas the hemorrhagic retinal detachment does not enhance (white arrowheads)
