Summary
This case report highlights a rare intraspinal extradural arachnoid cyst causing lumbar pain. Surgical removal led to significant symptom relief, demonstrating effective treatment for this uncommon spinal condition.
Area of Science:
- Neurosurgery
- Orthopaedic Surgery
- Radiology
Background:
- Spinal extradural arachnoid cysts are rare, potentially causing low back pain and radicular syndromes.
- These cysts may arise from arachnoid herniation through dural defects, possibly linked to hereditary factors or trauma.
- A ball-valve mechanism can contribute to cyst enlargement.
Observation:
- A 39-year-old female presented with intermittent radiating lumbar pain due to an intraspinal extradural arachnoid cyst at L3/4.
- Magnetic resonance imaging (MRI) confirmed the cyst's location and nature.
- The patient underwent surgical cyst resection and posterior lumbar interbody fusion (PLIF).
Findings:
- The patient experienced substantial relief from her symptoms following the surgical intervention.
- Complete surgical removal is crucial for minimizing recurrence risk.
- Interbody fusion is recommended when extensive decompression leads to instability.
Implications:
- Early diagnosis via MRI is key for effective management of spinal extradural arachnoid cysts.
- Surgical intervention, including cyst resection and potential fusion, can yield positive outcomes.
- Patient outcomes are influenced by age, symptom duration, and the extent of neurological damage.

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...

01:22Cerebral 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...
01:22Bacterial 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...
01:29Increased 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...
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,...
