Summary
This study presents a rare pediatric brain tumor case, a voluminous cavernoma in the ventricular trigone. The tumor exhibited a unique T2-weighted MRI finding, a hypointense rim, offering new insights into these rare lesions.
Area of Science:
- Neuro-oncology
- Pediatric Neurology
- Neuroradiology
Background:
- Cavernomas (cerebral cavernous malformations) are rare vascular malformations.
- Intracranial cavernomas predominantly occur in adults, with only 10 pediatric cases documented in the ventricular system.
Observation:
- A case of an 11-year-old girl with absence seizures is presented.
- The patient underwent surgery for a large cavernoma located at the ventricular trigone.
Findings:
- The cavernoma demonstrated a hypointense rim on T2-weighted magnetic resonance imaging (MRI).
- This specific MRI finding was uncommon in previously reported pediatric ventricular cavernoma cases.
Implications:
- Highlights the rarity of pediatric intraventricular cavernomas.
- Suggests that a hypointense rim on T2-weighted MRI may be a specific, albeit uncommon, imaging characteristic.
- Contributes to the understanding of neuroimaging in pediatric brain tumors.

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...
01:14Increased 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...
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...
