Congenital external hydrocephalus in a dog.
The Journal of Small Animal Practice
|April 30, 2019
Summary
A young Chihuahua experienced seizures and blindness due to external hydrocephalus, a condition involving cerebrospinal fluid buildup around the brain. This congenital issue affected the forebrain and cerebellum, requiring further investigation.
Area of Science:
- Veterinary Neurology
- Comparative Neurology
- Neuroimaging
Background:
- Progressive neurological signs including seizures, blindness, and lethargy in a young dog warrant thorough investigation.
- Neurolocalisation indicated a diffuse brain lesion impacting both the cerebrum and cerebellum.
Observation:
- Magnetic Resonance Imaging (MRI) revealed significant dilation of the subarachnoid space surrounding the cerebrum, filled with cerebrospinal fluid (CSF).
- Mild cerebral atrophy was suspected, and pachymeningeal contrast enhancement was noted.
- Cerebrospinal fluid analysis results were within normal limits.
Findings:
- The observed MRI findings were consistent with external hydrocephalus.
- The condition was suspected to be of congenital origin, meaning present from birth.
Implications:
- This case highlights the importance of advanced neuroimaging in diagnosing congenital brain abnormalities in dogs.
- Understanding external hydrocephalus in veterinary medicine can aid in early diagnosis and management strategies.
- Further research into the genetic or developmental factors causing congenital hydrocephalus in canines is warranted.

01:11Work Done on a System by External Force
2.9K
The work done by an external force on a particle changes its kinetic energy. However, internal forces must also be considered for a system of interacting particles. The potential energy formulation helps formulate the effect of internal forces. The net work done by an external force can be written in terms of the total change of mechanical energy, which includes both kinetic and potential energies.

01:24External and Internal Respiration
7.4K
External respiration occurs in the lungs, and it is the first step in the journey of oxygen inside the body. When we inhale, oxygen enters our lungs and diffuses across the thin alveolar membrane. The alveoli are tiny, air-filled sacs that provide a vast surface area for gas exchange. Oxygen in the alveoli has a higher partial pressure (105 mmHg) than in the adjacent pulmonary capillaries (40 mmHg), establishing a pressure gradient. As a result, oxygen molecules move from the alveoli into the...

01:12Internal and External Forces
16.2K
Newton's first law states that a net external force causes a change in motion. External forces act on an object or system, originating outside of the object or system. In contrast, internal forces originate inside the system of interest and do not lead to any acceleration. In simpler words, internal forces are forces that act on one part of an object and are exerted by another part of the same object. External forces are forces that act on an object due to some other object. Therefore, when...

01:21External Anatomy of the Kidney
3.5K
The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more...

01:26General External Flow Characteristics
529
The study of external flow is essential for creating structures and objects that interact efficiently and safely with moving fluids, such as air or water. When a body is immersed in a flowing fluid, it experiences two primary forces: drag, which opposes motion along the flow direction, and lift, which acts perpendicular to the flow. The shape, size, and orientation of the object influence these forces.Streamlined and Blunt Bodies in External FlowObjects in fluid flow are classified as...
