Insights

Pediatric intraventricular meningiomas are rare but can cause serious symptoms. This case highlights an atypical meningioma in a 5-year-old, emphasizing the need for prompt diagnosis and surgical removal.

Area of Science:

  • Neuro-oncology
  • Pediatric Neurosurgery
  • Neuropathology

Background:

  • Meningiomas are tumors arising from the meninges.
  • Intraventricular meningiomas are rare, particularly in pediatric populations.
  • Infantile meningiomas show a predilection for intraventricular locations compared to adults.

Observation:

  • A 5-year-old girl presented with symptoms of increased intracranial pressure and a cranial nerve VI palsy.
  • Brain imaging (CT and MRI) identified a lesion within the right lateral ventricle.
  • The lesion demonstrated significant enhancement following contrast administration.

Findings:

  • Surgical resection of the intraventricular tumor was successfully performed via a temporal lobe approach.
  • Histopathological examination confirmed the diagnosis of an atypical meningioma.

Implications:

  • This case underscores the importance of considering meningiomas in the differential diagnosis of pediatric intracranial masses.
  • Prompt surgical intervention is crucial for managing symptomatic intraventricular tumors in children.
  • Atypical meningiomas in pediatric patients warrant careful follow-up due to potential for recurrence.

Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
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: Introduction01:22

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...
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
