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...

Neuron Structure

Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each other using neurotransmitters at specific junctions called synapses. Neurons come in many shapes that often relate to their function, but most share three main structures: an axon and dendrites that extend out from a cell body.
Structure and Function of Neurons
The neuronal cell body—the soma— houses the nucleus and organelles vital to cellular...

Nervous Tissue: Glial Cells

Glia, or neuroglia, are vital support cells that assist neurons in their functions. The term "glia" originates from the Greek word for "glue," reflecting their role in holding the nervous system together. These cells can be categorized into six types: four in the central nervous system (CNS) and two in the peripheral nervous system (PNS).
The CNS glial cell includes the astrocytes, the oligodendrocytes, the microglia, and the ependymal cells.
Astrocytes are star-shaped glial cells that interact...

Area of Science:

  • Neuro-oncology
  • Neuroradiology
  • Pathology

Background:

  • Extraventricular neurocytoma (EVN) is a rare neuroepithelial tumor with a predilection for the cerebral hemisphere.
  • EVN shares histological similarities with central neurocytoma but exhibits more complex radiological characteristics.

Observation:

  • EVN cases often display ganglionic differentiation and cystic components.
  • Calcification is a frequent finding in EVN, while hemorrhage is less common.
  • Two cases presented as right frontal and right parietal lobe masses, showing specific MRI signal intensities and enhancement patterns.

Findings:

  • MRI revealed hypointensity on T1, hyperintensity on T2-weighted images, and moderate contrast enhancement.
  • The radiological complexity of EVN necessitates its inclusion in the differential diagnosis of intracranial masses.

Implications:

  • This study highlights the importance of considering EVN in the differential diagnosis of complex intracranial masses.
  • Understanding the distinct radiological features of EVN aids in accurate diagnosis and patient management.
  • Further research into EVN's pathogenesis and imaging characteristics is warranted.
