A 54-year-old female presented with spontaneous thoracic spinal cord herniation manifesting as chronic progressive motor weakness in both legs. Spastic paraparesis (4/5) and pathological reflexes such as ankle clonus were noted. She also had mild bladder dysfunction but no bowel dysfunction. She had no sensory disturbance, including tactile and pinprick sense. Magnetic resonance (MR) imaging revealed that the atrophic spinal cord was displaced into the ventral extradural space at the T4-5…

Ventral Thoracic Spinal Cord Herniation: A Commonly Misdiagnosed and Treatable Cause of Myelopathy
TLDR
A 36-year-old man presented to the authors' clinic with progressive leg weakness and spasticity in both legs and magnetic resonance imaging showed C-shaped anterior kinking of an atrophied spinal cord and enlarged dorsal subarachnoid space at the T5-T6 level.
Thoracic cord herniation through a dural defect: description of a case and review of the literature.
Ventral extradural spinal meningeal cyst causing cord compression: neurosurgical treatment.
TLDR
This is the first reported case of a spontaneous ventral extradural spinal meningeal cyst causing cord compression and Cyst-peritoneal shunt should be considered in cases in which complete resection of the cyst is made more difficult or risky by the need of more aggressive surgical maneuvers.
Idiopathic Spinal Cord Herniation Associated With a Thoracic Disc Herniation
TLDR
Although ISCH is a rare clinical condition that causes myelopathy, patients managed with surgery generally, though not universally, have a favorable neurological outcome, and an operative technique used to treat this condition is demonstrated.
Spinal Cord Herniation: Why Anterior Thoracic?
TLDR
The role of an anterior pulling force by the Hofmann (meningo-vertebral) ligaments is surmised; acting when the physiologic thoracic kyphosis suddenly increases; it allows the nipping/ protrusion of the spinal cord.
Idiopathic spinal cord herniation: diagnostic, surgical, and follow-up data obtained in five cases.
TLDR
Based on the results and complications in these five cases, the authors now believe that ISCH should be treated by using a dural patch to close the dural defect at the site of the herniation.
Idiopathic Thoracic Spinal Cord Herniation: Report of 10 Patients and Description of Surgical Approach
TLDR
Iiopathic spinal cord herniation presents with symptoms and signs of spinal cord dysfunction and a very characteristic imaging appearance, and can be treated safely, with the expectation of neurological stabilization and some improvement.
The value of intraoperative motor evoked potential monitoring during surgical intervention for thoracic idiopathic spinal cord herniation.
TLDR
The authors' documentation of acute loss of MEPs that correlated with reversible postoperative motor deficit substantiates the necessity of IOM including continuous monitoring of MEP's for the surgical treatment of TISCH.
Novel Strategy of Ventral Dural Repair for Idiopathic Thoracic Spinal Cord Herniation: Report of Outcomes and Review of Techniques.
TLDR
A unilateral dorsolateral, transpedicular approach combined with laminectomy provides excellent exposure for ventral or ventrolateral dural defects associated with idiopathic spinal cord herniation and minimizes spinal cord manipulation.
Diagnosis and treatment of spinal cord herniation: a combined experience.
TLDR
Patients presenting with a diagnosis of posterior intradural arachnoid cyst should be evaluated carefully for the presence of an anterior spinal cord herniation, and offering surgery to patients even when neurological compromise is advanced is recommended.

Herniation of the spinal cord. Case report.
TLDR
The authors suggest modifying the classification by Nabors, et al., of spinal meningeal cysts to include this mechanism of spinal cord herniation based on abnormal positioning of the spinal cord in the dural sleeve and the known anteroposterior movements of the cord that occur with cardiac and respiratory pulsations.
Spontaneous Thoracic Spinal Cord Herniation: A Case Report
TLDR
The patient improved after intradural reduction of the hernia and closure of the dural defect, and Idiopathic spinal cord herniation should be recognized as a cause of progressive myelopathy that can be managed successfully with microsurgical techniques.
Idiopathic spinal cord herniation. Report of two cases and review of the literature.
TLDR
The patients showed gradual improvement postsurgery, as did most of the patients in the previously reported cases, and the CSF flow and endoscopic studies were found to be particularly informative, and dural patching with surgical membrane is recommended.
Spinal cord herniation associated with an intradural spinal arachnoid cyst diagnosed by magnetic resonance imaging.
TLDR
The authors postulate that spinal cord herniation occurred for the following reason: the pressure of the intradural arachnoid cyst on the dorsal aspect of the spinal cord caused thinning of the dura, leading to a tear and, thus, the development of an extradural arACHnoid Cyst.
[A case of idiopathic herniation of the spinal cord associated with duplicated dura mater and with an arachnoid cyst].
TLDR
A 61-year-old man with a gradual loss of power in his lower extremities was diagnosed as intradural arachnoid cyst, and underwent operation, where a ventral part of the spinal cord was herniated from a defected area of the dural inner layer.
Idiopathic spinal cord herniation
TLDR
Four radiological signs of spinal cord herniation are described and the spinal cord was herniated into a cavity created by duplication of the dura mater and resection of the inner layer improved the neurological deficits.
Spinal cord herniation: report of two cases and review of the literature
TLDR
Iiopathic herniation of the spinal cord is an extremely rare disorder which may cause progressive myelopathy and CT myelography using thin slice sections is useful in the diagnosis of this disease.
Spinal cord herniation into a congenital extradural arachnoid cyst causing Brown-Séquard syndrome. Case report.
TLDR
Surgical correction of the spinal cord, which had herniated into a laterally located extradural arachnoid cyst and become incarcerated, resulted in a complete neurological recovery.
Idiopathic spinal cord herniation: a treatable cause of the Brown-Sequard syndrome--case report.
TLDR
Idiopathic herniation of the spinal cord is a treatable cause of the Brown-Sequard syndrome that may be more common than is currently recognized and should be known to all surgeons managing spinal disorders.
Spontaneous incarcerated herniation of the spinal cord into a vertebral body: a unique cause of paraplegia. Case report.
✓ A case of progressive paraparesis is reported in which the normal spinal cord herniated through a defect in the ventral meninges and dura and became incarcerated in a cavity in the dorsal aspect of…
