Cerebellum: Anatomical Regions

3.0K
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...

Cerebrospinal Fluid01:21

Cerebrospinal Fluid

3.8K
Cerebrospinal fluid (CSF) is a colorless liquid that flows around the brain and the spinal cord, playing a vital role in the protection, support, and overall function of the central nervous system (CNS). CSF production, circulation, and absorption are tightly regulated processes essential for the brain and spinal cord to function properly.
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain....

Cerebrum: Anatomical Overview I

3.6K
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...

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...

Epilepsy and Seizures: Overview

686
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Summary

Glioependymal cysts (GECs) are rare posterior fossa tumors. Surgical removal of a cerebellar GEC relieved a patient's headache and dizziness, confirming its clinical utility.

Area of Science:

  • Neuroscience
  • Pathology
  • Neurosurgery

Background:

  • Glioependymal cysts (GECs) are uncommon cystic lesions.
  • Posterior cranial fossa GECs present unique diagnostic and surgical challenges.

Observation:

  • A 36-year-old female presented with headache and dizziness due to a right cerebellar cystic lesion.
  • Radiological imaging revealed a well-defined, ovoid mass near the fourth ventricle.

Findings:

  • Surgical drainage and excision of the GEC resulted in complete symptom resolution.
  • Pathology confirmed the cyst wall comprised low cuboidal epithelium and glial cells.

Implications:

  • This case highlights the successful management of a posterior fossa GEC.
