Insights

Spontaneous chronic spinal subdural hematoma, a rare condition, can occur with arachnoiditis and syringomyelia. This case highlights a 76-year-old woman with a 14-year history of myelopathy, successfully treated with surgery.

Area of Science:

  • Neurosurgery
  • Neurology
  • Pathology

Background:

  • Spontaneous chronic spinal subdural hematoma (CSDH) is an uncommon neurological condition.
  • CSDH can present with progressive myelopathy, mimicking other spinal cord pathologies.
  • Association with arachnoiditis and syringomyelia is rarely reported.

Observation:

  • A 76-year-old woman presented with a 14-year history of progressive myelopathy.
  • Magnetic Resonance Imaging (MRI) revealed a thoraco-lumbar subdural cystic lesion and a thoracic syrinx.
  • Surgical intervention included laminectomy, decompression of the subdural hematoma, and myelotomy for syrinx drainage.

Findings:

  • Pathological examination confirmed a chronic subdural membrane.
  • Surgical decompression and syrinx drainage led to clinical improvement.
  • The case provides insight into the pathogenesis of spinal subdural hematoma and syrinx formation.

Implications:

  • This case underscores the importance of considering CSDH in patients with chronic myelopathy.
  • Understanding the pathogenesis may aid in earlier diagnosis and treatment of CSDH and associated syringomyelia.
  • Further research into etiological factors is warranted to elucidate the development of CSDH.

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Bacterial 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...
Brain Abscess l: Introduction01:26

Brain 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,...

Bacterial 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...

Cranial 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...
