Fundus photograph and fluorescein angiogram taken in November 1992. (A) Fundus photograph of the left eye showing an orange-yellow retinal tumor nasal to the optic disc. (B) Early phase showing hypofluorescence of the mass. (C) Late phase showing hyperfluorescence of the mass.

In the left posterior segment, there was an orange-yellow, partially pigmented mass nasal to the optic disc (Figure 1A). The mass was initially hypofluorescent, then exhibited late hyperfluorescence (Figure 1B and C) with fluorescein angiography (FA).
Fundus photograph, fluorescein angiogram, indocyanin green angiogram taken in April 1996. (A) Fundus photograph showing enlargement of the mass, hard exudates, and exudative retinal detachment. (B) Fluorescein angiogram showing hyperfluorescence of the tumor and exudative retinal detachment. (C) Indocyanin green angiogram showing intratumoral hyperfluorescence and the presence of intratumoral feeder vessels that seemed to be anastomosing with retinal vessels.

Figure 2A). FA of the tumor showed early hypofluorescence, late hyperfluorescence, and exudation (Figure 2B). Indocyanin green angiography revealed intratumoral hyperfluorescence and the presence of intratumoral feeder vessels that seemed to anastomose with retinal vessels (Figure 2C).
B-scan and A-scan ultrasonogram, computed tomography taken in April 1996. (A) B-scan ultrasonogram showing a solid mass measuring about 9.0 x 6.0 mm with exudative retinal detachment. A-scan ultrasonogram of the tumor, demonstrating medium to high internal reflectivity. (B) Computed tomography showing tumor located in the posterior pole.

B-scan ultrasonography showed a solid, elevated mass, which measured 9.0 x 6.0 mm, adjacent to the optic nerve with surrounding exudative retinal detachment (Figure 3A). CT confirmed the presence of an attenuating soft tissue mass in the posterior segment (Figure 3B).
Magnetic resonance image taken in April 1996. (A) T1-weighted axial magnetic resonance image of the tumor showing high intensity. (B) T2-weighted sagittal magnetic resonance image of the tumor showing low intensity. (C) Gadolinium-enhanced sagittal magnetic resonance image of the tumor showing enhancement.

On MRI, the tumor showed high intensity on T1-weighted images ( Figure 4A) and low intensity on T2-weighted images ( Figure 4B) with gadolinium enhancement (Figure 4C).
