Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

5.3K
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.

Cerebrospinal Fluid01:21

Cerebrospinal Fluid

3.2K
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....

Glaucoma: Overview01:25

Glaucoma: Overview

860
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Disorder of Water Balance01:29

Disorder of Water Balance

1.5K
Water balance disorders are medical conditions that occur when there is a deviation from the body's water volume or osmolarity, disrupting normal homeostasis and leading todehydration, hypotonic hydration, hyperhydration, edema, or water intoxication.
Dehydration
Dehydration occurs when the body loses fluids (particularly water).
Causes:
The major causes of dehydration include excessive sweating, fever, vomiting, diarrhea, and diuresis.
Signs and Symptoms:
Symptoms primarily include intense...

Heart Failure II: Pathophysiology01:29

Heart Failure II: Pathophysiology

76
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Area of Science:

  • Neurosurgery
  • Neurology
  • Medical Imaging

Background:

  • Hydrocephalus management often involves ventriculoperitoneal shunt placement.
  • Arachnoid cysts, particularly in the quadrigeminal cistern, can lead to hydrocephalus.
  • Shunt malfunction is a known complication requiring timely diagnosis.

Observation:

  • A 43-year-old woman presented with headache, nausea, and vomiting.
  • The patient had a history of ventriculoperitoneal shunt placement for hydrocephalus secondary to a quadrigeminal cistern arachnoid cyst.
  • Cranial CT revealed enlarged bilateral ventricles, indicating increased intracranial pressure.

Findings:

  • Abdominal radiography showed a fractured, reverse U-shaped peritoneal catheter.
  • The fractured shunt catheter was located in the left peritoneal cavity.
  • The shunt malfunction was the likely cause of the recurrent hydrocephalus and associated symptoms.

Implications:

  • This case highlights the importance of considering shunt integrity in patients with recurrent hydrocephalus symptoms.
  • Diagnostic imaging, including radiography, is essential for identifying mechanical shunt failures.
  • Prompt surgical intervention is necessary to repair or replace the fractured shunt, thereby resolving hydrocephalus and alleviating neurological deficits.
