BACKGROUND AND PURPOSE tSCH in the absence of spinal trauma or surgery is a rare disorder for which numerous mechanisms have been proposed. Here, we have conducted an analysis of images in all published reports of idiopathic tSCH and identified evidence supporting a pathogenesis in which anterior dural erosion at thoracic levels generates a CSF leak that pushes adjacent spinal tissue to tampona...

Introduction Metastatic spinal cord compression (MSCC) is defined as the compression of the dural sac and its contents by an extradural tumour mass.1 Improved oncological outcomes2 have resulted in more frequent presentation of MSCC.3 Autopsy data demonstrate spinal metastases in 70% of the commonest cancers and an the incidence of symptomatic MSCC in up to 10%.4 Successful treatment achieves m...

Spinal dural arteriovenous fistulas (SDAVF) account for about 70% of all spinal AV shunts. We report on a 56-year-old male patient with progressive neurological symptoms. Preand post-contrast MR imaging of the spine, including contrast-enhanced MR angiography was done on a 1.5 T MR scanner. In addition a special (pre-contrast) 3D turbo-spin-echo sequence with variable flip angle evolution (SPAC...

DURING MYELOGRAPHY WE OBSERVED THE CONTRAST MATERIAL IN THE SPINAL SUBARACHNOID SPACE WHILE WE CHANGED: (1) the intracranial blood volume by CO(2) inhalation, hyperventilation, and jugular vein compression; (2) the intra-abdominal and intrathoracic pressure by forced expiration with glottis closed; and (3) the CSF volume by withdrawals and reinjections of fluid. The spinal dural sac enlarges wi...

PURPOSE In patients with perimedullary arteriovenous fistula (AVF) with subarachnoid hemorrhage (SAH), knowledge of lesion location is necessary to select the appropriate approach for catheter spinal angiography. We evaluated the utility of 3-dimensional (3D) fast imaging with steady-state precession (FISP) sequence for detecting type 1 perimedullary AVF with SAH. MATERIALS AND METHODS We eva...

BACKGROUND Epidural hematomas, cerebrospinal fluid fistula, and spinal infections are challenging postoperative complications following vertebro-spinal procedures. We report our preliminary results using autologous fibrin sealant as both fibrin glue and a hemostatic during these operations. METHODS Prospectively, between January 2013 and March 2015, 68 patients received an autologous fibrin s...

Herniation of the spinal cord through a dural rent is a rare occurrence. Although sporadic cases have been documented, the diagnosis has never been made preoperatively [1 -3J . We report a case of a transdural cord herniation at the C1 C2 level. The dural tear was a result of penetration by a broken fracture-fi xation wire and its subsequent complications. Transdural spinal cord herniation was ...

Twenty-one patients with thoracolumbar spinal fractures were studied with computed tomography (CT). A vertebral body was involved in 20; 12 had additional fractures of the posterior elements. Five had multiple level injuries. Neurologic deficits occurred in nine and were more common in combined vertebral body and posterior element injury. Five patients had surgical exploration of the spinal can...

During spinal movements the dural end sac undergoes displacement and deformation, chiefly because of bulging of intervertebral disks and flaval ligaments in lumbar extension. Under normal circumstances these dural changes of form do not lead to clinical symptoms. However, in patients with spinal stenosis radiologic signs may be accentuated in lumbar extension. These tend to disappear in flexion...
