Abstract

AIM: To investigate whether congenital lumbar spinal stenosis (CLSS) is associated with a specific degenerative changes of the lumbar spine.

METHODS: The lumbar spine magnetic resonance imaging studies of 52 subjects with CLSS and 48 control subjects were retrospectively evaluated. In each examination, the five lumbar levels were assessed for the presence or absence of circumferential or shallow annular bulges, annular tears, anterior or posterior disc herniations, epidural lipomatosis, Schmorl’s nodes, spondylolisthesis, pars defects, and stress reactions of the posterior vertebral elements.

RESULTS: Compared to control individuals, subjects with CLSS exhibited increased incidence of circumferential and shallow annular bulges, annular tears, disc herniations and spondylolisthesis (P < 0.05).

CONCLUSION: CLSS is associated with increased incidence of degenerative changes in specific osseous and soft-tissue elements of the lumbar spine.

Core tip: Congenital lumbar spinal stenosis is associated with increased incidence of degenerative changes in specific osseous and soft-tissue elements of the lumbar spine. Describing the spectrum of the respective imaging findings, this article can assist radiologists in providing more detailed magnetic resonance imaging reports.
