Intraparenchymal hemorrhage is one form of intracerebral bleeding in which there is bleeding within brain parenchyma. The other form is intraventricular hemorrhage). [1] Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders.
Parenchyma (/ p ə ˈ r ɛ ŋ k ɪ m ə /) [1] [2] is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology , it is the tissue that fills the interior of flatworms .
Those with parenchymal contusion would require frequent follow-up imaging because such contusions may grow large enough to become hemorrhage and exerts significant mass effect on the brain. [3] Cerebral microhemorrhages is a smaller form of hemorrhagic parenchymal contusion and are typically found in white matter. Such microhemorrhages are ...
In ionic edema, the solute concentration of the brain exceeds that of the plasma and the abnormal pressure gradient leads to accumulation of water intake into the brain parenchyma through the process of osmosis. [1] The blood-brain barrier is intact and maintains the osmotic gradient. [21]
Bullae can become extensive and combine to form giant bullae. These can be large enough to take up a third of a hemithorax, compress the lung parenchyma, and cause displacement. The emphysema is now termed giant bullous emphysema, more commonly called vanishing lung syndrome due to the compressed parenchyma. [28]
In a study on the circle of Willis and its relation to cerebral vascular disorders, a comparison on various anomalies between normal brains (those without the condition of cerebral softening) and brains with cerebral softening were looked at to observe trends in the differences of the anatomical structure of the circle of Willis.
Crossed fused renal ectopia: One kidney crosses over to the opposite side and fuses with the other kidney. The abnormal orientation may obscure the renal sinus, leading to the faceless kidney sign. Multicystic dysplastic kidney (MCDK): A nonfunctional kidney with multiple cysts and absence of normal renal parenchyma. The lack of normal renal ...
Brain herniation frequently presents with abnormal posturing, [2] a characteristic positioning of the limbs indicative of severe brain damage. These patients have a lowered level of consciousness , with Glasgow Coma Scores of three to five.
