Jan 31, 2024 · MRI. Gliosis appears as an area with increased T2/FLAIR signal, somewhat reduced T1 signal and somewhat facilitated diffusion on ADC.

Feb 13, 2024 · Encephalomalacia is frequently used by radiologists to describe any area of cerebral parenchymal loss with or without surrounding gliosis.

Feb 16, 2015 · The eye of the tiger sign refers to symmetric bilateral abnormal low signal on T2-weighted MRI (due to abnormal accumulation of iron) in the globus pallidus with central high signal (due to gliosis and spongiosis). The eye of the tiger sign is most classically associated with pantothenate kinas...

A large area of encephalomalacia is present on the left side involving much of the temporal lobe, posterior frontal and parietal lobes with surrounding gliosis, consistent with an old MCA territory infarct.

Herpetic encephalitis can affect any age group, classically involve limbic system, insula, sub frontal area, and cingulate gyrus. The case was read as post encephalitis gliosis as per patient history.

Jun 24, 2024 · MRI. Mass effect and enhancement are often minimal despite large portions of the brain being involved. There is a loss of grey-white matter differentiation and diffuse gyral thickening. Diffuse T1 and T2 prolongation throughout both white and grey matter: T1: iso to hypointense to grey matter 1. T2: hyperintense to grey matter 1

Mar 10, 2025 · It is seen as a contiguous tract of gliosis leading from a region of cortical or subcortical neuronal injury towards the deep cerebral structures, along the expected topographical course of the involved white matter tract. MRI. Corresponding stages have been described on MRI 2,3. T1. stage 1: no changes. stage 2: T1 hyperintense. stage 3: T1 ...

Oct 16, 2024 · MRI. As with CT, the cyst appears well-defined and often corresponds to a vascular territory. The cyst is lined by white matter, which may or may not demonstrate evidence of gliosis (this depends on the age at which the insult occurred (see Pathology above), and is common in familial porencephaly).

Feb 16, 2015 · Perivascular spaces, also known as Virchow-Robin spaces, are fluid-filled spaces that surround small arterioles, capillaries and venules in the brain. Those that surround perforating vessels are frequently seen on routine MRI imaging. Despite having been described well over a century ago and se...

Feb 9, 2024 · MRI. Neuroglial cysts usually follow CSF signal. Hence, they are hypointense on T1 and hyperintense on T2. They do not enhance with gadolinium. They are usually suppressed on T2 FLAIR sequences. Differential diagnosis. General imaging differential considerations include: porencephalic cyst. communicates with the lateral ventricle
