Representative images of the wedge signs. The presence of a triangle shape of tissue between the lateral rectus muscle (red line) and lateral orbital wall (black line) is termed a lateral wedge sign, the histologic diagnosis was mucosa-assisted lymphoid tissue (MALT) lymphoma (a). The triangle tissue between the superior rectus muscle (red line) and roof of the orbit (black line) is termed a superior wedge sign, the histologic diagnosis was adenoid cystic carcinoma (b). The lateral wedge sign in immunoglobulin G4-related disease (c). The superior wedge sign in reactive lymphoid hyperplasia (d).
