Insights

Chronic subdural hematoma (CSH) can lead to severe complications. This study highlights two cases where CSH caused bilateral occipital lobe infarction, resulting in significant neurological deficits despite surgical intervention.

Area of Science:

  • Neurosurgery
  • Neurology
  • Radiology

Background:

  • Chronic subdural hematoma (CSH) is a common neurosurgical condition typically associated with favorable outcomes.
  • Surgical intervention, such as burr hole drainage, is the standard treatment for CSH.

Observation:

  • Two cases of CSH presented with delayed neurological deterioration.
  • Patients exhibited symptoms ranging from headache and impaired consciousness to coma and gait disturbance.
  • Brain CT scans revealed compressed ambient and interpeduncular cisterns, indicative of increased intracranial pressure and herniation.

Findings:

  • Both patients developed bilateral occipital lobe infarction, a rare but severe complication of CSH.
  • The infarction was attributed to central transtentorial herniation secondary to the mass effect of the bilateral CSH.
  • Despite prompt burr hole drainage, patients experienced severe neurological sequelae.

Implications:

  • This case series underscores the potential for CSH to cause devastating neurological injury beyond typical outcomes.
  • Occipital lobe infarction due to herniation highlights the critical importance of timely diagnosis and management of CSH.
  • Neurosurgeons and neurologists should consider this rare complication in patients with CSH presenting with neurological decline.

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...

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...
Cerebral Edema ll: Pathophysiology01:22

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...

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...

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,...
