Computed tomography (CT) confirmed the central venous thrombosis and significant retrograde dilatation of the left axillosubclavian and external jugular veins (Figure 2 A, B), with retrograde flow in the cavernous sinus and superior ophthalmic vein and subsequent proptosis of the left eye (Figure 3).
Computed tomographic image shows dilatation of the left superior ophthalmic vein and proptosis of the left eye in relation to an increased retrograde venous flow.
