Glioblastomas are the most common primary malignancies to hemorrhage while thyroid, renal cell carcinoma, melanoma, and lung cancer are the most common causes of hemorrhage from metastatic disease. Other causes of intraparenchymal hemorrhage include hemorrhagic transformation of infarction which is usually in a classic vascular distribution and ...
Behçet's disease is recognized as a disease that causes inflammatory perivasculitis, inflammation of the tissue around a blood or lymph vessel, in practically any tissue in the body. Usually, prevalent symptoms include canker sores or ulcers in the mouth and on the genitals , and inflammation in parts of the eye. [ 3 ]
On CT scans, brain parenchymal hemorrhage that does not confined to specific arterial territory along with hyperdense appearance on dural venous sinuses raises the suspicion of DVST. Further evaluation with CT venography, MR venography, and post gadolinium MRI provides accurate diagnosis of venous thrombosis and follow-up after treatment.
Neurocysticercosis can be classified into two main types: parenchymal, which affects the brain tissue, and extraparenchymal, which occurs outside the brain tissue. [37] Parenchymal neurocysticercosis: neurocysticercosis lesions within brain parenchyma. [37] Viable parenchymal cysts: contains the scolex, typically between 0.5 and 2 cm in ...
Cerebral edema is a major cause of brain damage and contributes significantly to the mortality of ischemic strokes and traumatic brain injuries. [4] [9] As cerebral edema is present with many common cerebral pathologies, the epidemiology of the disease is not easily defined. [1]
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. [7] It is also known to contain collagen proteins. [8] Damage or trauma to the brain parenchyma often results in a loss of cognitive ability or even death.
Viruses, bacteria, and other infectious agents activate the body's defense systems and cause immune cells to protect the designed area from the damage. Some of these foreign pathogens can trigger a strong inflammatory response that can compromise the integrity of the blood-brain barrier and thus change the flow of inflammation in nearby tissue.
Huntington's disease is a degenerative neurological disorder that is inherited. Degeneration of neuronal cells occurs throughout the brain, especially in the striatum. There is a progressive decline that results in abnormal movements. [31] Statistics show that Huntington's disease may affect 10 per 100,000 people of Western European descent.
