Idiopathic Spinal Cord Herniation Diagnosis and Treatment

Idiopathic spinal cord herniation (ISCH) is displacement of the thoracic spinal cord through a dural defect, giving rise to progressive myelopathy. It most commonly affects middle-aged adults, who present with back pain, sensory disturbances and motor weakness often exhibiting Brown-Séquard syndrome. High-resolution MRI is the diagnostic cornerstone, revealing ventral displacement, focal cord kinking and altered cerebrospinal fluid (CSF) spaces. Differential considerations include arachnoid web, intradural cysts and extramedullary masses, each capable of producing similar radiological features. Surgical repair remains the definitive treatment: approaches range from enlargement of the dural defect to duraplasty with patch grafting and careful microsurgical reduction of the herniated cord. Early intervention is associated with better neurological recovery, whereas delayed surgery may result in incomplete functional restoration. Postoperative imaging typically demonstrates stable realignment of the cord, although signal changes can evolve over time. Rare complications such as extradural fluid collections and pial siderosis may arise, highlighting the need for methodical follow-up. Advances in imaging protocols, operative techniques and interdisciplinary collaboration continue to drive improvements in outcomes and enhance global recognition of this rare but treatable condition.

The graph below shows the total number of articles in idiopathic spinal cord herniation diagnosis and treatment across all publications each year (not limited to Nature Index journals).

Technical terms

Herniation: The protrusion of neural tissue through a defect in the dura mater.

Dura mater: The tough outer membrane that envelops the spinal cord and brain.

Brown-Séquard syndrome: A clinical syndrome marked by ipsilateral motor weakness and contralateral sensory loss below the level of a spinal lesion.

Duraplasty: A surgical repair technique involving grafting or patching the dura to close a defect.

Magnetic resonance imaging (MRI): A non-invasive imaging modality that uses magnetic fields to produce detailed images of soft tissues.

Cerebrospinal fluid (CSF): The clear fluid that surrounds the brain and spinal cord, providing cushioning and nutrient transport.
