B-scan USG in the right eye revealed a hyperechoic choroidal lesion causing acoustic shadowing (Figure 3).
On US, the appearance also mimics IDC-NOS, manifesting as a hypoechoic solid mass with ill-defined margins and posterior acoustic shadowing. MRI shows characteristics of a malignant tumor, more commonly an irregular mass with a type 3 enhancement curve (rapid initial rise, followed by a drop-off with time/washout in the delayed phase) [8, 9].
