Isolating Central Nervous System Tissues and Associated Meninges for the Downstream Analysis of Immune cells
Published on: May 19, 2020
Is meningocele really an isolated lesion?
Summary
Dorsal meningocele often hides other spinal lesions. Whole spine MRI is crucial for diagnosis, and surgery is needed to address these occult findings and prevent neurological deficits.
Area of Science:
- Neuroscience
- Pediatric Neurosurgery
- Spinal Imaging
Background:
- Dorsal meningocele is a congenital spinal anomaly.
- Associated occult spinal lesions can complicate management.
- Early diagnosis and treatment are vital for preventing neurological sequelae.
Purpose of the Study:
- To investigate the prevalence and types of occult spinal lesions associated with dorsal meningocele.
- To evaluate the diagnostic utility of whole spine Magnetic Resonance Imaging (MRI).
- To determine optimal surgical strategies for managing these complex spinal malformations.
Main Methods:
- Retrospective analysis of two patient groups: newly diagnosed dorsal meningocele and post-operative meningocele with neurological decline.
- Comprehensive whole spine MRI was performed on all participants.
- Surgical treatment included addressing associated spinal cord malformations and tethered cord syndrome.
Main Results:
- The conus medullaris terminated below the L3 vertebral level in all patients.
- Commonly identified associated lesions included tight filum, split cord malformation, epidermoid tumors, dorsal lipomas, and hydromyelia.
- Ninety percent of newly diagnosed patients had at least one associated spinal lesion, with 6 patients having multiple lesions.
Conclusions:
- Dorsal meningocele frequently conceals additional, occult spinal pathologies.
- Whole spine MRI is essential for comprehensive evaluation.
- Microsurgical techniques are necessary for accurate diagnosis and treatment of tethering bands and associated anomalies to prevent further neurological damage.

01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:22Cerebral 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...
