Summary
A Toy Poodle with seizures had an intracranial ectopic choroid plexus cyst removed. This first-of-its-kind surgery resolved the dog's seizures for 18 months.
Area of Science:
- Veterinary Neurology
- Comparative Pathology
Background:
- Status epilepticus is a neurological emergency in dogs.
- Intracranial cysts can cause significant neurological deficits.
Observation:
- A 4-year-old Toy Poodle presented with status epilepticus and delayed postural reactions.
- MRI revealed a cystic lesion compressing key brain structures.
Findings:
- Surgical removal of an intracranial ectopic choroid plexus cyst was performed.
- The cyst was located in the mesencephalon, hippocampus, and amygdala.
Implications:
- This is the first reported case of successful surgical removal of an intracranial ectopic choroid plexus cyst in a dog.
- Complete seizure resolution was achieved for 18 months post-surgery, indicating a favorable prognosis for similar cases.

Spinal Nerves: Plexus I
2.8K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

Spinal Nerves: Plexus II
2.4K
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Dimensional Analysis
64.2K
Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

Reproductive Cloning
32.7K
Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...
