Fig. 13

A 40-year-old man with a pigmented ciliary body melanoma of the left eye. The same patient as in Fig. 1. Axial (a) fat-suppressed T1-weighted and (b) contrast-enhanced fat-suppressed T1-weighted images illustrate an hyperintense mass along the anterior aspect of the globe (white arrows). After contrast agent administration, the lesion enhancement is hardly detectable due to the intrinsic hyperintensity of the lesion on pre-contrast T1-weighted image. On (c) axial DW image (b = 1000 s/mm2) and (d) corresponding ADC map the lesion exhibits restricted diffusion with high signal intensity (white arrow) on DWI image and low signal intensity (black arrow) on ADC map, a finding consistent with high cellularity
