Summary
Delayed brain herniation through a subdural membrane is a rare complication, even years after neurosurgery. Prompt surgical intervention is crucial for recovery and preventing permanent neurological damage.
Area of Science:
- Neurosurgery
- Neurology
- Oncology
Background:
- Reports a rare case of delayed cerebral herniation through a subdural membrane in an adult patient.
- Highlights the rarity of brain herniation as a complication of chronic subdural hematomas post-neurosurgery.
Observation:
- A 54-year-old patient with a history of oligodendroglioma developed acute hemiparesis and aphasia.
- Imaging revealed suspected brain herniation through a membrane in the middle cranial fossa.
- Exploratory surgery confirmed incarcerated brain herniation through a membrane with a ring-like aperture.
Findings:
- Resection of the membrane normalized brain position and led to clinical improvement.
- This case represents delayed local herniation over a year after neurosurgical procedures.
Implications:
- Brain herniation through a subdural membrane is an extremely rare complication.
- Consider this diagnosis in patients with known subdural hematoma/hygroma and clinical deterioration, irrespective of recent surgery.
- Urgent surgical intervention is recommended to mitigate risks of permanent neurological damage.

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...
01:22Cerebral 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...
01:26Brain 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,...
01:29Hemorrhagic 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...
01:14Increased 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...
