The pathophysiology, classification, treatment, and prognosis of a spontaneous thoracic spinal cord herniation: A case study with literature review

چکیده
BACKGROUND Spinal cord herniation was first described in 1974. It generally occurs in middle-aged adults in the thoracic spine. Symptoms typically include back pain and progressive paraparesis characterized by Brown-Séquard syndrome. Surgical reduction of the hernia improves the attendant symptoms and signs, even in patients with longstanding deficits. CASE DESCRIPTION A 66-year-old female with back pain for 7 years, accompanied by paresthesias and a progressive paraparesis, underwent a thoracic MRI which documented a ventral spinal cord herniation at the T4 level. Following a laminectomy, with reduction of the hernia and ventral dural repair, the patient improved. CONCLUSION Herniation of the thoracic cord, documented on MR, may produce symptomatic paraparesis which may resolve following laminectomy with ventral dural repair.

Spontaneous Resolution of Symptomatic Thoracic Spine Calcified Disc Herniation: A Case Report and Literature Review
Calcification of intervertebral disc (IVD) is an uncommon but well-defined clinical syndrome in children. Despite its benign nature, occasionally, calcified nucleus pulposus can herniate into the spinal canal. We report an interesting case of calcified disc herniation in the thoracic spine. Although it resulted in cord compression and syrinx formation, it well responded to conservative manageme...

Background & Importance: Disc herniation is defined as the prolapsed of material disc into the spinal canal. If the disc fragment is free in spinal canal, it is called sequestration disc fragment. Occasionally, alteration in sequestration disc fragment makes the diagnosis of the disc herniation, challenging. Case Presentation: We reviewed a rare case of the cervical sequestrated disc...

Epidermoid cyst in the spinal cord is a rare condition. It constitutes of only 0.6-1.1% of all spinal tumors. When they occur, the typical location is in the subdural, extramedullary space of the lumbo-sacral region.We report a forty-two -year-old female who presented with left extremity radicular pain and myelopathy. MRI of the thoracic spine,illustrated a focal fusiform enlargement of the tho...

Background: Brown-Sequard syndrome (BSS) is a rare neurological condition resulting from a hemisection injury to or unilateral compression on the spinal cord. The most common causes of BSS that are amenable to be treated surgically can be divided into traumatic and non-traumatic injuries. Traumatic injuries are often reported as the main cause of BSS. However, non-traumatic injuries of the spin...
