What is brain parenchymal signal abnormality?

The etiology of parenchymal signal abnormalities associated with DVAs in adults and children is incompletely understood. Prior investigators have suggested that abnormal FLAIR signal intensity may represent edema or gliosis secondary to chronic venous insufficiency/hypertension related to anomalous venous drainage.

What does brain parenchyma mean?

The brain parenchyma refers to the functional tissue in the brain that is made up of the two types of brain cell, neurons and glial cells. It is also known to contain collagen proteins. Damage or trauma to the brain parenchyma often results in a loss of cognitive ability or even death.

What does parenchymal abnormality mean?

What is left of the brain after parenchyma?

The remaining brain tissue is known as stroma, which is the supportive or structural tissue. Damage or trauma to the brain parenchyma often results in a loss of cognitive ability or even death.

What are the different types of brain parenchyma?

A number of different conditions can affect the brain parenchyma. Changes due to age, deterioration, trauma, or damage to the stroma can cause a wide range of conditions, including dementia, Alzheimer’s, Parkinson’s disease, epilepsy, multiple sclerosis, and Amyotrophic Lateral Sclerosis (ALS).

What does it mean to have diffuse parenchymal volume loss?

Diffuse parenchymal volume loss means there is shrinkage in the size of your brain, however nothing to panick about it as it can be a normal ageing process or can also be due to decrease in blood supply to your brain or also there are various other conditions which can cause this sort of picture.
