Cranial and Spinal Meninges

4.5K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Spinal Cord: Gross Anatomy

6.8K
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

Summary

The degree of calcification in spinal meningiomas impacts surgical outcomes. Extensive calcification is linked to higher surgical morbidity, while microcalcifications may indicate better outcomes.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Oncology

Background:

  • Spinal meningiomas are tumors arising from the meninges surrounding the spinal cord.
  • Calcification is a common feature in spinal meningiomas, potentially influencing surgical approach and outcomes.
  • Understanding factors affecting surgical morbidity is crucial for patient management.

Purpose of the Study:

  • To analyze surgical outcomes in patients with calcified spinal meningiomas.
  • To identify factors associated with surgical morbidity in this patient cohort.

Main Methods:

  • Retrospective analysis of 54 patients who underwent surgical resection for spinal meningioma between 2000 and 2013.
  • Histopathologic confirmation of calcification in 37 cases.
  • Neurologic status assessed using the American Spinal Injury Association Impairment Scale (ASIA) and analyzed for improvement (NSI).

Main Results:

  • A significant relationship was found between neurologic status improvement (NSI) and the degree of meningioma calcification.
  • Microcalcified meningiomas showed a direct relationship with NSI.
  • Ossified meningiomas demonstrated an inverse relationship with NSI, suggesting increased morbidity.

Conclusions:

  • The degree of spinal meningioma calcification is a significant factor influencing postoperative outcomes.
  • Extensive tumor calcification may be associated with increased surgical morbidity.
  • Further investigation into the impact of calcification patterns on surgical outcomes is warranted.
