Lumbosacral intradural periradicular ossification. Case report

Journal of Neurosurgery

|July 1, 1978

Summary

Intradural ossification is rare, typically affecting the thoracic spine. This case highlights its unusual occurrence in the lumbosacral region, causing significant low back pain and sciatica.

Area of Science:

Spinal Pathology
Radiology

Background:

Intrathecal ossification, the formation of bone within the spinal canal, is an uncommon condition.
It frequently leads to progressive myelopathy or radiculopathy, neurological deficits resulting from spinal cord or nerve root compression.
Most reported cases involve the thoracic spine, with sacral canal involvement being rare.

Observation:

This report details a case of a previously healthy male experiencing severe low back pain and sciatica.
The symptoms were attributed to intradural periradicular ossification specifically in the lumbosacral region.
This presentation is unusual given the typical location of such ossifications.

Findings:

The study documents a rare instance of ossification within the spinal canal affecting the lumbosacral nerve roots.
This finding challenges the conventional understanding of the common anatomical locations for intrathecal ossification.
The ossification directly correlated with the patient's debilitating symptoms of low backache and sciatica.

Implications:

This case expands the known spectrum of spinal ossification presentations.
It underscores the importance of considering lumbosacral intradural ossification in the differential diagnosis of persistent sciatica and low back pain.
Further research may be warranted to understand the etiology and optimal management of this rare condition in the lumbar region.
