Summary
Rhabdoid meningioma, a rare tumor variant, can occur in recurrences. This case presents the first reported instance of intraventricular rhabdoid meningioma following a fibroblastic meningioma.
Area of Science:
- Neuro-oncology
- Pathology
- Neurosurgery
Background:
- Meningiomas are tumors arising from the meninges.
- Rhabdoid meningioma is an aggressive, rare variant.
- Intraventricular meningiomas occur within the brain's ventricles.
Observation:
- A 55-year-old woman presented with headache and tinnitus 5 years post-resection of an intraventricular fibroblastic meningioma.
- Imaging revealed a recurrent intraventricular tumor.
- Histological examination confirmed the presence of rhabdoid meningioma.
Findings:
- This represents the first documented case of intraventricular rhabdoid meningioma.
- The tumor recurred as a different histological subtype.
Implications:
- Highlights the potential for meningioma recurrence with varying histology.
- Suggests the need for vigilance in monitoring intraventricular meningioma survivors.
- May inform future diagnostic and treatment strategies for rare meningioma variants.

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...

01:18Anatomy 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...
