A and B, Pre- (A1 and A2) and postoperative (B1 and B2) sagittal (A1 and B1) and axial (A2 and B2) T2-weighted MR images from a patient with SS show a significant decrease in a longitudinally extensive fluid-filled collection anterior to the spinal cord after repair of a dural defect at T11. The site of the dural defect was localized by a dynamic CT myelogram. A1 and B1 reprinted with permission from Kumar N. Superficial siderosis: associations and therapeutic implications.
