ependyma

The width of the TV [Figure 2] was calculated by measuring the distance between the inner boundaries of both hyperechoic lines of ependyma at the thalamus level.[sup][17] A TV width >7/10 mm in patients under/over 60 years old was regarded as an enlarged ventricle.[sup][18] To exclude bias, TV values were independently calculated by a second sonologist who was blinded to the patient diagnosis.

Aquaporin 4 (AQP4) is a member of a water channel protein family expressed primordially in the end feet of astrocytes at the border with the capillary network, the glia limitans and central canal ependyma [18], and the regulation of its expression might underlie some mechanistic actions of MP administration after SCI.

(a) Contrast-enhanced (CE) axial transverse fluidattenuated inversion-recovery (FLAIR) view at admission showing diffuse abnormal enhancement of ependyma (white arrow) and bilateral fluid-fluid level at trigonal areas of lateral ventricles (black arrow).

suggested that these cysts originate from neuroepithelium, like ependyma and choroid plexus, hence the term neuroepithelial cyst [6]; however, in 1992, Tsuchida et al.

We also investigated the distribution of coilin in the ventricular ependyma of e15.5 embryonic brains.

The cystic spaces, immediately adjacent tissues, meninges, and ependyma contained variable numbers of yeast associated with a granulomatous inflammatory response or a pleocellular population of lymphocytes, plasma cells, macrophages, and neutrophils (Figure).

It can not only clearly display intracranial anatomical structure, but can also precisely position.5,6 Primary lymphoma mostly starts from cerebral hemisphere, and 70% ~ 80% are supratentorial focuses locating in deep white matter, callosum, basal ganglia and thalamus, some of which also involves pia mater and ependyma.7,8

The ventricular catheter was stuck to the ependyma and was unable to remove at the time of the second surgery, so the ventricular catheter was kept in situ and a new shunt system was inserted.
