Summary
Classical syringomyelia theories are outdated. Greitz's intraspinal pulsation pressure theory offers a better explanation, particularly for cases linked to Arnold-Chiari syndrome and cerebrospinal fluid flow obstruction.
Area of Science:
- Neurology
- Neurosurgery
- Pathophysiology
Context:
- Syringomyelia pathogenesis theories have evolved.
- Classical theories by Gardner and Williams are now largely disproven.
- Cerebrospinal fluid circulation disturbances are key.
Purpose:
- To review and evaluate current hypotheses on syringomyelia pathogenesis.
- To highlight the relevance of intraspinal pulsation pressure theory.
- To discuss the role of Arnold-Chiari syndrome in syringomyelia.
Summary:
- Greitz's intraspinal pulsation pressure theory provides a plausible mechanism for syringomyelia.
- This theory is particularly relevant in cases involving obstacles to cerebrospinal fluid flow, such as in Arnold-Chiari syndrome.
- Narrowing of the posterior fossa and arachnoid spaces contributes to Arnold-Chiari syndrome.
Impact:
- Supports surgical interventions aimed at restoring cerebrospinal fluid spaces and flow at the cranio-cervical junction.
- Offers a more accurate understanding of syringomyelia, guiding future research and clinical practice.
- Provides a framework for investigating the link between posterior fossa anatomy and syringomyelia development.

01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
01:19Cranial and Spinal Meninges
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...

01:23Cirrhosis I: Introduction
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
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...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
