Abstract Ligamentum flavum cyst of the lumbar spine has seldom been described. The mechanism formation these cysts remains unknown, but it is thought to be part degenerative process. Although they are clearly visible on imaging studies, frequently wrongly diagnosed as ganglion or synovial cysts. Bone erosion rarely associated with this pathology. Most common symptom back and radicular pain due ...

An 8-year-old Warmblood gelding presented with a history of progressive ataxia for 6 weeks. Intra- and intervertebral ratios measured from lateral radiographs the cervical spine were within normal limits. Computed tomographic myelography revealed focal compression dorsal ventral contrast column as well displacement spinal cord canal due to bulging soft tissue attenuating material in half juncti...

Ossification of the ligamentum flavum is a rare cause of thoracic myelopathy. It develops in East Asians more frequently than in people from other areas. The exact pathophysiology has not been elucidated yet; however, it largely depends on biomechanical alterations, especially changes in the tensile force. Because the spinal cord is compressed from the posterior side, the first and most common ...

We describe two cases of degenerative intraspinal cyst of the cervical spine that caused a gradually progressive myelopathy. One case had a cyst that arose from the facet joint and the other case had a cyst that formed in the ligamentum flavum. The symptoms improved immediately after posterior decompression by cystectomy with laminoplasty.

This report describes a special case of thoracic spinal canal stenosis, which is rarely mentioned in the literature. Thoracic spinal canal stenosis is unusual because it is caused by comprehensive elements and involves multiple segments of the thoracic spine. Compared with the cervical spinal stenosis and lumbar spinal stenosis, thoracic spinal canal stenosis has lower morbidity. This patient u...
