    Insights

    Interhemispheric subdural empyema is a rare intracranial infection presenting with increased ICP and focal seizures. Surgical drainage via burr hole or excision led to complete recovery in all six young patients.

    Area of Science:

    • Neurology
    • Neurosurgery
    • Infectious Diseases

    Background:

    • Interhemispheric subdural empyema is an uncommon and potentially severe intracranial infection.
    • This condition can arise from various infectious sources and primarily affects younger individuals.

    Purpose of the Study:

    • To report on six cases of interhemispheric subdural empyema.
    • To describe the characteristic clinical symptoms and diagnostic imaging findings.
    • To evaluate the efficacy of surgical treatment and patient outcomes.

    Main Methods:

    • Case series reporting on six patients under 24 years old.
    • Clinical presentation, including intracranial infection, increased intracranial pressure (ICP), cerebral falx syndrome, and focal seizures, was documented.
    • Diagnostic imaging utilized included angiography and computed tomography (CT) scans.
    • Surgical interventions involved continuous drainage via cranial burr hole or abscess excision.

    Main Results:

    • Patients presented with characteristic symptoms of intracranial infection, elevated ICP, cerebral falx syndrome, and focal seizures.
    • Angiography and CT scans accurately localized the subdural empyema lesions.
    • All six patients underwent successful surgical treatment.
    • No recurrence of the empyema was observed post-treatment.

    Conclusions:

    • Interhemispheric subdural empyema, though rare, is manageable with prompt diagnosis and surgical intervention.
    • Accurate localization using imaging modalities is crucial for effective treatment.
    • Surgical drainage or excision offers a high success rate with no recurrence.

    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 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...
    Bacterial Meningitis II: Pathophysiology01:26

    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,...
    Cerebral Edema l: Introduction01:19

    Cerebral Edema l: Introduction

    Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
    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...
