a-e Initial presentation. a OCT showing subretinal fluid, elevated choroid, and atrophic ONL (horizontal black bar in d shows corresponding area of fundus). b Axial T1 MRI showing hyperintense, thickened choroid and detachment. c Transverse B-scan showing bullous retinal detachment and irregular choroidal thickening. d Color fundus image showing choroidal mass lesion (arrowheads) and retinal detachment (arrows). e Sub-RPE and choroidal mass are highlighted with increased autofluorescence in the RPE. f-h 4.5 months after EBRT. f Color fundus showing mass regression, as well as prominent choroidal vasculature, RPE hyperplasia, and residual scarring. g OCT showing regression of mass and absence of subretinal fluid, along with some RPE atrophy and subretinal scar (horizontal black bar in f shows corresponding area of fundus). h Transverse B-scan showing mass regression and resolution of retinal detachment.

Dilated examination of the right eye revealed a retinal detachment and an amelanotic subretinal mass extending from the posterior pole and tapering into the periphery (fig. 1). OCT demonstrated residual subretinal scarring (fig. 1).
a Fine needle aspirate showing small lymphocytes, scattered pigmented and nonpigmented cells, and proteinaceous material (cell block HE; magnification x1,000). b Immunohistochemical stain showing CD20 B lymphocytes (magnification x1,000). c Immunohistochemical stain showing few CD3 T lymphocytes (magnification x1,000).
