(A) B-ultrasound images showed an intraretinal macrocyst and a detached retina (arrow). The size of the intraretinal macrocyst was approximately 12.64 x 10.42 mm. (B) Orbital MRI revealed a moderate-enhancing mass (arrow) in T1 images in the vitreous cavity of the right eye. (C) Orbital MRI revealed a hyper-enhancing mass (arrow) in T2 images in the vitreous cavity of the right eye. The hyper-enhancing mass was approximately 12.44 x 9.50 mm. (D) The lesion (arrow) was located in the posterior lower part of the vitreous cavity on sagittal scans.

A shallow, straight hyperechoic band was continuous with the mass wall and attached to the eyeball wall at the other end (Figure 1A). T1 images (Figure 1B) and a hyper-enhancing mass in T2 images (Figure 1C) in the vitreous cavity of the right eye. They both had the same enhancement as the abnormal vitreous body of the right eye, accompanied by a hypo-enhancing smooth wall. In addition, the presence of the same hypo-enhancing band connected the mass to the wall of the eye (Figure 1D).
(A, B) The giant cyst was located in the inferior peripheral area from 4 to 8 o'clock. (C) There was a clear boundary of epithelial atrophy (white arrow) between the detached retina and the normal one. (D) After removing the upper retina, we can see the apparent cyst wall. (E) Colored crystalline fluid (green arrow) flowed from the cyst when the retina and the wall were incised. (F) The pathological results of the cyst wall revealed a small amount of retinal tissue and pigmentation (white triangle). (G) The abscission cytology test of the crystalline liquid excluded the presence of nucleated cells. (H) Six months after the first surgery, the retina had been repositioned. The boundary between the normal retina and the detached retina that appeared earlier could be visualized (blue arrow).

The giant cyst was located in the inferior peripheral area from 4 to 8 o'clock (Figures 2A,B). There was a clear boundary of epithelial atrophy between the detached retina and the normal one (Figure 2C). Instead, we identified an apparent cyst wall (Figure 2D). Colored crystalline fluid, instead of blood, flowed from the cyst when the retina and the wall were incised (Figure 2E). The pathological results of the cyst wall revealed a small amount of retinal tissue and pigmentation (Figure 2F). The abscission cytology test of the crystalline liquid excluded the presence of nucleated cells (Figure 2G). The boundary between the normal retina and the detached retina that appeared earlier could be visualized (Figure 2H).
