At the region where the wall of the hemisphere is attached to the roof of the diencephalon, the wall of the telencephalon is thin, formed of a single layer of
ependymal cells covered by vascular mesenchyme, and together they form the choroid plexus of the lateral ventricle (Fig.
Identity crisis for adult periventricular neural stem cells: subventricular zone astrocytes,
ependymal cells or both?
GFP was visualized in
ependymal and adjacent cells at 24 h postinjection.

Pyogenic ventriculitis is an inflammation of the ciliated
ependymal lining of the brain's ventricles, leading to an accumulation of pus within the ventricles themselves [5].

The
ependymal nature of these curious neoplastic cells was also not evident; however, we incidentally came across some canalicular formations lined by ciliated cylindrical cells exhibiting the same vacuolative changes as the signet-ring-like ones (Figure 2(e)).
An immunohistological examination revealed that the specimen lacked arachnoid and
ependymal cells (recognized as epithelial membrane antigen- (EMA-) positive cells) as well as glia cells (recognized as glial fibrillary acidic protein(GFAP-) positive cells).
This revealed a rounded, heterogeneous, soft tissue mass with central calcifications opposing the
ependymal surface in the ventral body of the right lateral ventricle measuring approximately 12 mm x 18 m.
