Focal anterior displacement of the spinal cord out of the dural sac through a dural defect at the T7 level. At this location, there is an ill-defined focus of T2 hyperintensity in the cord. There is no posterior mass effect on the posterior thecal sac to favor a posterior arachnoid cyst.
Case Discussion
In this case, there is no mass effect, no relevant history or signs of disc pathology, so the imaging features are consistent with idiopathic spinal cord herniation.
