Diastematomyelia is a "dysraphic state" of unknown embryonic origin, but is probably initiated by an accessory neurenteric canal (an additional embryonic spinal canal.).) This condition may be an isolated phenomenon or may be associated with other segmental anomalies of the vertebral bodies such as spina bifida, kyphoscoliosis, butterfly vertebra, hemivertebra and block vertebrae which are ...
Lumbosacral transitional vertebrae consist of the process of the last lumbar vertebra fusing with the first sacral segment. [1] While only around 10 percent of adults have a spinal abnormality due to genetics, a sixth lumbar vertebra is one of the more common abnormalities. [2] Sacralization of the L5 vertebra is seen at the lower right of the ...
The conus medullaris (or lower termination of the spinal cord) normally terminates at or above the L1-2 disk space (where L1 is the first, or topmost lumbar vertebra). After about 3 months of age, a conus below the L1-2 disk space may indicate a tethered cord and termination below L3-4 is unmistakably tethered.
It is a congenital disorder in which the fetal development of the lower spine—the caudal partition of the spine—is abnormal. [1] It occurs at a rate of approximately one per 60,000 live births. [2] Some babies are born with very small differences compared to typical development, and others have significant changes.
The biggest difference is whether the infant is symptomatic at time of presentation to a health professional. If the infant is still showing symptoms, then the condition is termed an ALTE. In order to be considered a BRUE, the infant should be completely asymptomatic at time of presentation, which is more common.
Dural ectasia can be asymptomatic, in which case no intervention is necessary. However, it is associated with chronic pain in patients with Marfan syndrome, suggesting it is a structural risk factor. [20] There is no medical consensus on how to manage symptomatic (painful) dural ectasia.
Vertebral hemangiomas are observed throughout any age, although most are diagnosed in people within their 50s alongside a higher presence in females with a 1:1.5 male-to-female ratio. They often present in the vertebral body of the thoracic and lumbar spine with potential to extend into the posterior arch. They can involve a single or multiple ...
[3] [5] The tract may terminate in the deep fascia, or even make contact with neural elements. [2] Congenital dermal sinus may form at any point along the midline of the neuraxis, however, the majority form in the lumbar and lumbosacral region (41% and 35% of cases respectively). [3]
