Idiopathic anterior herniation of the thoracic cord: a review.

Idiopathic spinal cord herniation (ISCH) is a rare condition caused by a defect in the dura mater, resulting in ventral displacement of the spinal cord. Its etiology is not fully understood, but it mainly affects middle-aged women and manifests as progressive myelopathy. Surgical treatment is the best option to avoid neurological worsening. This report presents a case of spinal cord herniation in a 45-year-old man, complaining of numbness for 4 months, with paraparesis that progressed to gait disorder. This condition was diagnosed by magnetic resonance imaging and computed tomography. The patient underwent T2 to T3 laminectomy, hernia reduction, and duroplasty, with successful resolution of the condition.
