Figure 2 Plain CT. (A) showing a relatively low-density mass of the fundus measuring 5 cm x 4 cm in diameter, contrast-enhanced CT revealing no positive enhancement of this mass-like lesion in its early (B) and late (C) phases, MRI showing a mass in the fundus with a slightly low intensity on T1-weighted images (D) and a slightly high intensity on T2-weighted images (E). White arrow represents the mass-like lesion of the fundus.
