Figure 2d. Endophytic retinoblastoma in a 2-year-old boy with left leukocoria who had impaired vision in the left eye at ophthalmologic examination. (a) Photograph of the sectioned gross specimen shows a pinkish white mass in the posterior globe that abuts the retina (arrowhead) and has a nodular cut surface. * = lens. (b) Axial unenhanced computed tomographic (CT) image shows the nodular hyperattenuating mass (arrow), which occupies the posterior left globe and contains foci of calcification. (c) Axial T2-weighted magnetic resonance (MR) image shows that the tumor is fairly homogeneous and hypointense relative to the vitreous. (d, e) MR images (d obtained at a higher level than e) acquired with intravenous contrast material but without fat saturation show that the mass is hyperintense relative to the adjacent vitreous.
