Lumbar Intervertebral Disk Degeneration and Patient Age
N.L. Marinelli V.M. Haughton P.A. Anderson BACKGROUND AND PURPOSE: T2 relaxation times provide a continuous measure of changes in intervertebral disk biochemistry. The purpose of this study was to correlate T2 relaxation times in lumbar disks with patient age and stage of degeneration. MATERIALS AND METHODS: Sagittal T1and T2-weighted images and axial images were acquired in 20 patients referre...
متن کاملLumbar diskal cyst containing intervertebral disk materials.
The diskal cyst is a relatively new clinical entity and develops clinical symptoms of a unilateral single nerve root lesion. Although many cases of diskal cyst have been reported, the pathogenesis of diskal cyst remains unclear, and several theories regarding the pathogenesis have been proposed. This article presents 2 cases of diskal cyst communicating with an adjacent herniated disk. Magnetic...

متن کاملLateral disk herniation into the lumbar intervertebral foramen: differential diagnosis.
Lateral disk herniation into the intervertebral foramen if not recognized may result in a negative surgical exploration. The condition is readily recognized by computed tomography (CT), which demonstrates a soft-tissue mass in the intervertebral foramen, focal protrusion of the posterolateral margin of the disk into the foramen, absence of dural sac deformity, and occasionally the presence of c...
متن کاملIntervertebral-disc lesions: a new etiological concept.
ur knowledge of the pathology of the intervertebral discs is a modern development, mostly within the last quarter century. It is more than likely that lesions of these structures were equally if not more prevalent in earlier times, but were not generally recognized until X-ray technique became a major factor in physical diagnosis. Another reason for non-recognition of these lesions may have bee...
