Figure 4b. Bilateral retinoblastoma in 10-month-old boy. (a) Transverse T1-weighted MR image (480/15) of left eye obtained after gadolinium-based contrast agent administration shows hyperintense enhancing ring, which appears to be a diffuse thickened choroid, probably related to inflammation secondary to an intraocular tumor (arrows). (b) Microscopic specimen shows a detail of optic nerve (O), choroid (C), and sclera (S). Inflammatory cells, present in choroid, caused MR image enhancement. (Hematoxylin-eosin stain; original magnification, x20 objective.)
