: A sample of 512 Chinese was studied and we observed that greater disc degeneration on MRI was associated with greater spine DXA BMD. Yet, this association may be confounded by facet joint osteoarthritis. BMD may not be a risk factor for lumbar disc degeneration in Chinese. PURPOSE: Evidence suggested that lumbar vertebral bone and intervertebral disc interact with each other in multiple ways. The current paper aims to determine the association between bone mineral density (BMD) and lumbar disc degeneration using a sample of Chinese...

BACKGROUND: Medulloblastoma (MB) is the most common malignant brain tumor of childhood, with cerebrospinal fluid spread the most common site of metastasis. Currently, children diagnosed with MB and evidence of spinal metastasis are treated with an increased dose of craniospinal radiation (CSI). This report reviewed equivocal abnormalities including nerve root clumping, linear vascular enhancement, nerve root enhancement and/or other vague findings on spinal magnetic resonance imaging (MRI) to elucidate their prognostic significance and aid in risk stratification...

Most spinal cord injury is seen with trauma. Nontraumatic spinal cord emergencies are discussed in this chapter. These myelopathies are rare but potentially devastating neurologic disorders. In some situations prior comorbidity (e.g., advanced cancer) provides a clue, but in others (e.g., autoimmune myelopathies) it may come with little warning. Neurologic examination helps distinguish spinal cord emergencies from peripheral nervous system emergencies (e.g., Guillain-Barré), although some features overlap...

OBJECTIVE Image guidance for spinal procedures is based on 3D-fluoroscopy or CT, which provide poor visualization of soft tissues, including the spinal cord. To overcome this limitation, the authors developed a method to register intraoperative MRI (iMRI) of the spine into a neuronavigation system, allowing excellent visualization of the spinal cord. This novel technique improved the accuracy in the deployment of laser interstitial thermal therapy probes for the treatment of metastatic spinal cord compression...

BACKGROUND CONTEXT: The ability to adequately measure a phenomenon is critical to studying and understanding it. Since 1957, a variety of subjective visual grading methods have been used to assess disc degeneration, but have been limited by gross ordinal scales and imprecision, as well as suboptimal reliability. Conceptually sound, objective, precise measurements are needed to advance knowledge of disc degeneration and its causes, progression and consequences. PURPOSE: To investigate the reliability and validity of a new system ('SpIn' for Spine Insight) to quantitatively measure lumbar disc degeneration or pathology...

Chordoma is a rare, indolent but locally invasive, osteolytic, slow growing, low grade, primary bone malignancy, derived from the embryonic remnants of the notochord. It is a midline tumour and it predominantly emerges from the axial skeleton. The most commonly observed location of a chordoma is in the sacrococcygeal region ( 50 to 55% ) followed by the cranio occipital region ( 25 to 30% )We present a case of a 30 years old lady who came to us with complaints of difficulty in walking and inability to hold objects in both hands...

Reported is a case of a man aged 55 years who presented with progressive spastic paraparesis. Examination demonstrated multiple cutaneous telangiectases. Subsequent development of upper limb weakness, acute urinary retention and eventual respiratory compromise resulted in the requirement for intensive care unit admission and mechanical ventilation. MRI spine revealed diffuse T2 hyperintensity in the cervical cord with enhancement and cord expansion. Immunomodulatory therapy for a presumed diagnosis of transverse myelitis yielded no response, so a vascular aetiology was suspected...

Spinal intramedullary tuberculoma is a rare cause of spinal cord compression. We report a case that had an intramedullary spinal cord tuberculomas where the diagnosis was made by MRI and biopsy. The clinical presentation was that of a cord compression in a 30-year-old male febrile patient. This case of intramedullary spinal tuberculoma with a longitudinally extending lesion of the cervicothoracic spine from C4 to D8 is presented for the rarity of its presentation.

STUDY DESIGN: A retrospective case review of patients who underwent 18F sodium fluoride PET/CT imaging of the spine with postoperative pain following vertebral fusion. OBJECTIVE: To determine the benefit of 18F sodium fluoride PET/CT imaging in the diagnosis of persistent pain in the postoperative spine. The diagnosis of pain generators in the postoperative spine has proven to be a diagnostic challenge. The conventional radiologic evaluation of persistent pain after spine surgery with the use of plain radiographs, MRI, and CT can often fall short of diagnosis in the complex patient...

BACKGROUND AND PURPOSE: Spinal anatomy has been variably investigated using 3D MRI. We aimed to compare the diagnostic quality of T2 sampling perfection with application-optimized contrasts by using flip angle evolution (SPACE) with T2-FSE sequences for visualization of cervical spine anatomy. We predicted that T2-SPACE will be equivalent or superior to T2-FSE for visibility of anatomic structures. MATERIALS AND METHODS: Adult patients undergoing cervical spine MR imaging with both T2-SPACE and T2-FSE sequences for radiculopathy or myelopathy between September 2014 and February 2015 were included...

INTRODUCTION: Synovial cysts of the cervical spine are rare. These lesions have been associated with other spinal conditions as osteoarthritis, spondylolisthesis, and disc degeneration, with authors postulating a possible link with segmental spinal instability. This study aims to describe an atypically presenting case of a cervical synovial cyst. CASE REPORT: A 65-year-old man presented with complaints of cervical radicular pain (VAS of 7) that evolved with development of paresthesia and muscular weakness, compatible with C8 right compression...
