Presentation transcript:

(A) Initial MR venography demonstrated partial thrombosis of the superior sagittal sinus, torcula, and proximal transverse sinuses (arrows). (B) Follow-up MR venography at the time of visual worsening showed improvement in venous flow, with mild residual thrombosis. (C) Fast-spin echo T2-weighted axial imaging demonstrated reversed optic nerve cupping in the right eye with posterior scleral flattening and protrusion of optic nerve papilla into the globe (arrow) (subsequent image on MRI demonstrated similar findings in the left eye). (D) Close-up of right eye seen in (C). MRI data: (A and B) repetition time (TR) 33.3 msec, echo time (TE) 6.9 msec, ST 1.5 mm; (C and D) TR 3500 msec, TE 95 msec, ST 5.0 mm.
