Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

10.7K
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.

Vesicular Tubular Clusters01:45

Vesicular Tubular Clusters

3.3K
After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.
With the help of motor proteins such...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Cerebrospinal Fluid01:21

Cerebrospinal Fluid

7.6K
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....

Pinching-off of Coated Vesicles01:32

Pinching-off of Coated Vesicles

4.4K
Vesicle budding is orchestrated by distinct cytosolic proteins such as adaptor proteins, coat proteins, and GTPases. To initiate vesicle budding, membrane-bending proteins containing crescent-shaped BAR domains bind to the lipid heads in the bilayer and distort the membrane to form a protein-coated vesicle bud. Adaptors proteins such as AP2 for clathrin-coated vesicles can nucleate on the deformed membrane. Finally, coat proteins such as clathrin or COPI and COPII assemble into a coat forming...

Area of Science:

  • Neurosurgery
  • Neuropathology
  • Radiology

Background:

  • Colloid cysts are the most frequent neoplastic lesions found in the third ventricle.
  • Multiple colloid cysts within the ventricular system are exceptionally rare.

Observation:

  • A 35-year-old female presented with obstructive hydrocephalus due to paired colloid cysts in the third ventricle.
  • Surgical intervention was performed using the transcallosal interhemispheric transforaminal approach.

Findings:

  • This represents the first reported case of dual colloid cysts exclusively within the third ventricle.
  • Previously, only three cases of paired colloid cysts in different ventricles have been documented.

Implications:

  • Highlights the necessity of thorough radiologic evaluation for colloid cyst diagnosis.
  • Emphasizes complete preoperative planning and surgical excision of all colloid cysts to prevent recurrence.
