2024年8月28日 · Cortical laminar necrosis, also known as pseudolaminar necrosis, is necrosis of cortical neurons in situations when the supply of oxygen and glucose is inadequate to meet regional demands. This is often encountered in cardiac arrest, global hypoxia and hypoglycemia.

Cortical mineralization is fairly common following stroke and should not be mistaken for cortical laminar necrosis which refers to damage limited to specific layers of the cortex.

2016年4月13日 · Cortical laminar necrosis, also known as pseudolaminar necrosis, is necrosis of cortical neurones in situations when the supply of oxygen and glucose is inadequate to meet regional demands. This is often encountered in cardiac arrest, global hypoxia and hypoglycaemia.

2024年10月6日 · T1 hyperintensities indicating cortical laminar necrosis become evident after two weeks. This hyperintense signal does not represent hemorrhage, and it is believed to be caused by the accumulation of denatured proteins in dying cells.

2021年8月18日 · Gyral enhancement, also known as gyriform, cortical, or grey matter enhancement, is a pattern of contrast enhancement in the superficial brain parenchyma that conforms to the serpentine morphology of the cerebral gyri.

The evolution of infarction from edema to cortical laminar necrosis and hemorrhagic tarnsformation to atrophy are all well demonstrated in this case.

2021年10月3日 · Cerebral cortical T1 hyperintensity or gyriform T1 hyperintensity refers to curvilinear hyperintense signal involving the cerebral cortex on T1-weighted images on brain MRI. Causes include: accumulation of denatured proteins and/or lipid-laden macrophages. cortical laminar necrosis 2; accumulation of methemoglobin in cortical hemorrhagic infarcts

2024年1月5日 · Cerebral cortical restricted diffusion, also known as gyriform restricted diffusion, cortical ribboning or cortical ribbon sign, refers to curvilinear hyperintense signal involving the cerebral cortex on DWI images with a corresponding low signal on ADC images.

2020年12月19日 · Although being a rare finding on imaging, Morel laminar sclerosis is seen mainly in the lateral-frontal cortices, showing typical signs of cortical laminar necrosis on MRI: T2/FLAIR: cortical hyperintensity; DWI/ADC: high signal seen on …
