Insights

Interhemispheric cysts are rare brain lesions in infants, sometimes associated with corpus callosum agenesis. This case highlights diagnostic findings in an infant presenting with increased head circumference.

Area of Science:

  • Pediatric Neurology
  • Neuroradiology
  • Developmental Neuroscience

Background:

  • Interhemispheric cysts are uncommon pediatric intracranial lesions.
  • These cysts can occur with or without agenesis of the corpus callosum.
  • While often asymptomatic, they can present with symptoms due to mass effect.

Purpose of the Study:

  • To present a case of interhemispheric cyst in an infant.
  • To illustrate the magnetic resonance imaging findings associated with this rare condition.

Main Methods:

  • Case report of an 11-month-old female infant.
  • Magnetic resonance imaging (MRI) was utilized for diagnosis.

Main Results:

  • The infant presented with an increased head circumference.
  • MRI revealed findings consistent with an interhemispheric cyst.

Conclusions:

  • Interhemispheric cysts require careful diagnostic evaluation in infants presenting with relevant symptoms.
  • MRI is crucial for identifying and characterizing these rare cystic lesions.

Cerebral Hemispheres01:05

Cerebral Hemispheres

The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

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...

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.

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
