Cerebrum: Anatomical Overview I01:26

Cerebrum: Anatomical Overview I

The main and largest component of the human brain is the cerebrum. The cerebrum consists of two main parts: the cerebral cortex, an outer layer with wrinkles or folds known as gyri and shallow grooves called sulci, and a deeper region beneath it. The cerebrum divides into two distinct hemispheres and contains five different lobes: the frontal, parietal, temporal, occipital, and insula. The central sulcus separates the frontal and parietal lobes and two functionally important gyri — the...

Cerebellum: Anatomical Regions

The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal to the brainstem. It plays a significant role in motor control, coordination, and proprioception.
Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis. The...

Cerebral 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...

Cerebrum: Anatomical Overview II

Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...

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...

Summary
This summary is machine-generated.

A rare brain tumor, gliomatosis cerebri, affected a 6-year-old boy after an encephalitis-like illness. Despite aggressive symptoms, treatment was refused, leading to rapid decline and death within six months.

Area of Science:

  • Neuroscience
  • Pediatric Oncology
  • Neuropathology

Background:

  • Gliomatosis cerebri is a rare, diffuse primary brain tumor characterized by infiltration of glial cells throughout the cerebral white matter.
  • Pediatric gliomatosis cerebri presents unique diagnostic and therapeutic challenges due to its rarity and aggressive nature in young patients.

Observation:

  • A 6-year-old boy developed progressive hemiplegia, behavioral changes, and seizures following an encephalitis-like illness.
  • Neuroimaging (MRI) demonstrated diffuse signal abnormalities and swelling predominantly in the left cerebral hemisphere.

Findings:

  • Brain biopsy confirmed the diagnosis of gliomatosis cerebri.
  • The patient's condition rapidly deteriorated following the diagnosis.

Implications:

  • This case highlights the aggressive progression of pediatric gliomatosis cerebri and the critical need for timely diagnosis and treatment.
  • The refusal of radiotherapy in this case underscores the complex interplay between medical recommendations and parental decisions in pediatric oncology.
  • Further research into novel therapeutic strategies for gliomatosis cerebri is warranted to improve outcomes in affected children.
