Idiopathic spinal cord herniation through the inner layer of duplicated anterior dura: evaluation with high-resolution 3D MRI.
We report a case of idiopathic spinal cord herniation through the inner layer of duplicated anterior dura. High-resolution three-dimensional (3D) MRIs clearly depicted the duplicated dura mater ventral to the spinal cord and herniation of the cord through the inner layer of dura mater, which was confirmed at surgery. Presurgical high-resolution 3D MRI thus enables precise determination of the site of cord herniation in patients with this condition.
