Ependymal pseudorosette
Photomicrograph of brain tissue (H&E stain)
Tumor cells (cylindrical epithelium) are arranged in a radial manner around several vessels. This pattern is called a perivascular pseudorosette.
Perivascular pseudorosettes are a hallmark of ependymoma.
Ependymoma
Photomicrograph of ependymal tissue (H&E stain)
There is an abnormally high number of cells with round nuclei and abundant cytoplasms. Some cells are arranged in a spoke-and-wheel pattern, surrounding an empty central lumen. Such patterns are called ependymal rosettes (example indicated by green overlay).
Other cells are arranged concentrically around vessels, producing a similar appearance (perivascular pseudorosettes; example indicated yellow overlay).
Ependymoma
Cranial MRI (FLAIR-sequence, sagittal view)
A hyperintense, heterogeneous, extended mass is visible on the roof of the 4th ventricle (white outline). At the superior aspect of the tumor, multiple cysts are present (white arrows). As a result of an obstructed circulation of the cerebrospinal fluid, the 3rd ventricle appears widened.
This is a typical radiologic presentation and location of ependymoma.
