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 ...

PURPOSE To evaluate the clinical importance of nerve root enhancement associated with lumbar disk herniation. METHODS Thirty-two patients with lumbar disk herniation were examined with unenhanced and contrast-enhanced MR imaging. We investigated the relationship between nerve root enhancement and location of herniated disk in the epidural space, onset pattern of symptoms, subsequent treatment...

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 ...

BACKGROUND AND PURPOSE Ionic solutes diffuse more slowly in cartilage than do nonionic ones. The purpose of this study was to test the hypothesis that the contrast between scar and recurrent herniated disk fragment on MR images is greater after the IV administration of an ionic rather than a nonionic contrast medium. METHODS Patients who had undergone previous laminectomy and who had MR imagi...

Microdiscectomy is considered a very safe procedure with few serious complications. Ureteric injury following microdiscectomy is rarely reported in the literature. We report a rare case of iatrogenic ureteric injury following L5-S1 microdiscectomy for prolapsed intervertebral disc which was detected early and managed in time.

A group of 40 patients with symptoms of prolapsed lumbar disk, seven of which were recurrent after surgery, was studied by computed tomography. In all cases, the diagnosis was confirmed by myelography and posterior surgery. Computed tomography was performed after the disappearance of myelographic contrast medium. Positive herniated disk was shown by computed tomography in 88%. In postoperative ...

Making use a linear operator, which is defined here by means of the Hadamard product (or convolution) involving the generalized hypergeometric function, we introduce two novel subclasses Qp,q,s(α1;A,B,λ) and Qp,q,s(α1;A,B,λ) of meromorphically multivalent functions of order λ (0 λ < p) in the punctured disc U∗ . In this paper we investigate the various important properties and characteristics o...

PURPOSE Our goal was to compare contrast enhancement of recurrent herniated disk fragments and scar after intravenous injection of a new high-molecular-weight contrast medium, Gadomer 17 (gadomer), with that after injection of a low-molecular-weight contrast medium, (gadopentetate dimeglumine). METHODS Recurrent herniated disks were modeled in dogs by placing a fragment of intervertebral disk...

We present a 75-year-old man who, for 2 weeks, had progressive pain in both of his thighs when standing straight. MR imaging showed a sequestrated disk fragment, which had a signal intensity similar to that of a herniated disk with a rim enhancement in the posterior epidural space and a ruptured outermost annulus of the intervertebral disk at L2-3. Awareness of these MR imaging findings can hel...
