An intravertebral pneumatocyst is a relatively rare condition, and its natural course and etiology are unclear. We report a case of intravertebral pneumatocysts in the C5 vertebra that gradually enlarged during a 16-month period as documented by follow-up CT. In addition, direct communication was observed between the gas in the intervertebral disk and another pneumatocyst in the C6 vertebral bo...

Herniation of the intervertebral disk is a common cause of neurological dysfunction in the dog, particularly in the Dachshund. Using the Illumina CanineHD BeadChip, we have previously identified a major locus on canine chromosome 12 nucleotide positions 36,750,205-38,524,449 that strongly associates with intervertebral disk calcification in Danish wire-haired Dachshunds. In this study, targeted...

A 7-year-old Dachshund was presented with chronic left thoracic limb lameness and acute neurological deficits to the hind limbs following trauma. A lesion was suspected between C7 and T2 on the basis of neurological examinations. Radiography and myelography identified a calcified intervertebral disk at C7-T1 and an extradural unilateral compressive lesion at T1-2. Computed tomography scans of t...

BACKGROUND AND PURPOSE Experimental studies have shown that solutes diffuse more slowly into degenerated intervertebral disks than into normal disks. A noninvasive clinical study of diffusion in intervertebral disks is not generally available. Our purpose was to evaluate contrast-enhanced MR images to study diffusion in normal and degenerated lumbar intervertebral disks. METHODS The change in...

PURPOSE To compare MR contrast enhancement of intervertebral disk tissue after intravenous administration of equimolar doses of an ionic and of a nonionic gadolinium complex. METHODS Contrast enhancement was measured on MR in lumbar intervertebral disks for 120 minutes after intravenous injection of gadoteridol or gadopentetate dimeglumine, 0.3 mmol/kg. MR studies were performed with each con...

PURPOSE To determine the feasibility of measuring diffusion into human intervertebral disks by means of MR imaging with an intravenous nonionic gadolinium complex (gadoteridol). METHODS In 18 patients undergoing lumbar spine MR imaging, signal intensity was measured in the intervertebral disks after a dose of 0.1 mmol/kg and after a supplemental dose of 0.2 mmol/kg. RESULTS Signal intensity...

In the original description of herniated intervertebral disk by Mixter and Barr [1), the term used was rupture of the inter-vertebral disk. However, with the passage of time, this term, although used frequently by surgeons, has become meaningless. A rupture of the disk is a common finding at autopsy when the disks are examined, but ruptures are not necessarily associated with herniation of the ...

UNLABELLED The complexity of the clinical, biochemical, hystochemical and immunologic aspects of the intervertebral disk, along with its molecular biology, justifies the object of our study on the extracellular matrix modifications in lumbar disk hernias and their impact on patient quality of life. MATERIAL AND METHOD The research lot was composed of 50 patients, aged between 18 and 73, who h...

Herniated thoracic intervertebral disk causing spinal cord compression with paraparesis is uncommon in adults and rare in children. This article describes a case of pediatric thoracic disk herniation with paraparesis treated surgically.A 14-year-old girl presented with a 4-month history of diffuse back pain and sudden onset paraparesis. Motor strength was 4/5 in both legs, and she had lost the ...

Disk inflammation in children is believed to result from infection, and Staphylococcus aureus is reported to be the organism most commonly isolated from cases of intervertebral disk infection. A case of disk inflammation caused by the unusual pathogen Kingella kingae is described. The antibiotic susceptibility of other K. kingae isolates and the clinical features of 11 other previously reported...
