Spinal Cord: Gross Anatomy

Spinal Cord: Gross Anatomy

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...

Cerebral Edema ll: Pathophysiology

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...

Summary

Spinal cavernous angiomas, rare vascular malformations, can occur within the spinal canal. This case highlights an unusual intradural cauda equina cavernous angioma with intraneural growth in a lumbar radiculopathy patient.

Area of Science:

Neurology
Neurosurgery
Vascular Malformations

Background:

Spinal cavernous angiomas are uncommon vascular malformations, typically found in the vertebral body.
Less than 5% of these lesions are exclusively within the spinal canal, presenting in extradural, intradural-extramedullary, or intramedullary locations.

Observation:

A 75-year-old woman presented with symptoms of multiple lumbar radiculopathy.
Lumbosacral magnetic resonance imaging (MRI) revealed an intradural cauda equina lesion with heterogeneous contrast enhancement.

Findings:

The lesion was surgically removed via L3-L4 laminectomy.
Microscopic examination confirmed a cavernous angioma with intraneural growth, a rare presentation.
This represents one of only 12 reported cases of such lesions.

Implications:

This case expands the understanding of spinal cavernous angioma locations and presentations.
Highlights the importance of considering rare vascular lesions in the differential diagnosis of lumbar radiculopathy.
Contributes to the limited literature on intradural cauda equina cavernous angiomas with intraneural involvement.
