Summary
Childhood third ventricle meningiomas are rare. This case highlights successful surgical removal of a transitional meningioma in a child, leading to an uneventful recovery without the need for a permanent shunt.
Area of Science:
- Pediatric Neurosurgery
- Neuro-oncology
- Neuropathology
Background:
- Meningiomas are uncommon in children, with third ventricle locations being exceptionally rare.
- Only 16 cases of third ventricle meningiomas in pediatric patients have been previously reported in medical literature.
Observation:
- A 5-year-old girl presented with headache and bilateral papilledema, indicative of increased intracranial pressure.
- Imaging revealed a large mass in the third ventricle causing hydrocephalus.
Findings:
- The tumor, attached to the choroid plexus, was completely removed via a transcallosal interfornical approach.
- Histopathological examination confirmed the diagnosis of a transitional meningioma.
- The patient experienced an uneventful recovery, avoiding the need for a permanent cerebrospinal fluid shunt.
Implications:
- CT and MRI are valuable for diagnosing third ventricle meningiomas and planning surgical interventions.
- Complete surgical excision is the primary curative treatment for these rare pediatric tumors.
- This case contributes to the limited literature on pediatric third ventricle meningiomas, emphasizing successful surgical outcomes.

01:18Anatomy 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...
01:19Cranial 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...

01:18Viral 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...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
