Fundus photography. (a) Right eye within normal limits, (b) left eye with visible mass located inside the boundary of the temporal arcade, (c) wide field photography of the left eye, (d) fundus autofluorescence of the left eye revealing the mass lesion with autofluorescent properties.

The RE fundus was unremarkable (Fig. 1A). A dilated fundus examination of the LE revealed a large, central, dome-shaped, nonpigmented subretinal lesion temporal to the disc measuring approximately 6 disc diameters covering an area within the temporal arcades with an accumulation of subretinal fluid (Fig. 1B, C, D).
B scan ultrasonographic image of the mass lesion. (a) The lesion can be seen temporal to the disc (white arrowheads), (b) largest dimension of the mass lesion.

Shallow exudative detachment and the absence of choroidal excavation or thickened adjacent sclera were observed (Fig. 2).
Optical coherence tomography of the left eye illustrating the dome-shaped solitary nodular lesion and multifocal exudative detachment of the retina.

Optical coherence tomography (OCT) examination revealed multifocal exudative retinal detachment with increased choroidal thickening (Fig. 3).
Fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA). (a) Early-phase images reveal blocked hypofluorescence of the choroidal mass with multiple leakage sites within and surrounding the mass. (b) Late-phase images show diffuse hypofluorescence with multiple pinpoint leakage sites seen with FFA and pooling of dye with ICGA, suggestive of exudative detachment.

ICGA demonstrated diffuse hypofluorescence corresponding to the area of exudative detachment in the early phase with multiple pinpoint hyperfluorescence in the late phase (Fig. 4).
Magnetic resonance imaging of the orbit. (a, b) T1-weighted hyperintensity of the lesion, (c) T2-weighted image revealing hypointense mass lesion, (d) post gadolinium contrast image showing diffuse enhancement of the lesion as well as enhancement of surrounding periocular tissue posterior to the globe.

The lesion demonstrated diffuse hyperintensity in T1-weighted scans (Fig. 5 A, B) and hypointesity in T2 images (Fig. 5 C). Post contrast, there was diffuse enhancement of the lesion and focal enhancement of the overlying periocular soft tissue (Fig. 5 D).
Fundus photograph and corresponding optical coherence tomography of the left eye after 1 year. The lesion has completely regressed and near-normal restoration of the foveal anatomy was achieved.

Follow up was conducted for a year following the diagnosis, and at the end of the year (October 2020), the choroidal lesion had completely regressed (Fig. 6).
