case_images: A 24-year-old man presented with conjunctival injection (a), pain, and visual loss. He was found to have an amelanotic choroidal mass (b) and panuveitis. Ultrasound evaluation using B-scan demonstrated a dome-shaped mass located temporally, measured 12* 9*6.7 mm, with primarily high internal reflectivity and a mound of tissue with variable reflectivity and a well-bordered mass inside the main lesion. (c) In UBM, the mass had variable internal reflectivity with cystic alterations and spread anteriorly to the iris root (d). Fluorescein angiography revealed optic nerve head leakage, posterior and peripheral vasculitis, and staining of the lesion (e).

case_images: On the temporal side of OS, diffuse conjunctival injection with localized scleral and episcleral thickening were found with dilated (sentinel) vessels on the temporal side (Figure 1(a)). 2+ anterior chamber (AC) and anterior vitreous (AV) reactions were also detected. In the far peripheral region of the superotemporal area of the retina, a subretinal creamy-white mass with a cuff of subretinal fluid (SRF) was found (Figure 1(b)). On ultrasonography, a choroidal mass with a diameter of 12 x 9 x 6.7 mm was seen with a primarily high internal reflectivity and a mound of tissue with variable reflectivity and a well-bordered mass inside the main lesion that extended anteriorly to the ciliary body (Figures 1(c) and 1(d)).
case_images: Two weeks following therapy, slit-lamp examination revealed reduced conjunctival injection and scleral edema (a), fundus examination demonstrated significant decrease in mass size and subretinal white deposits with trace SRF at the site of resolved mass (b), and b-scan also showed resolution of choroidal mass with small amount of subretinal fluid (c).

case_images: SRF amount decreased in a few days, and after two weeks, his BCVA improved to 2/10, the AC and AV inflammation decreased to trace cells, and the mass size decreased significantly as it could hardly be seen in the fundus examination and B-scan. Subretinal white deposits with trace SRF at the site of resolved mass were visible (Figures 2(a)-2(c)).
