A forum dedicated to the expansion in neuropathology knowledge for students and practitioners alike.
Although meningiomas are classically dura-based lesions, they can also arise in the choroid plexus and, thus, must be considered in the differential diagnosis for intraventricular lesions. This intraventricular meningioma, shown here, is growing underneath normal choroid plexus epithelium.
Ependymomas are glial tumors that commonly harbor perivascular pseudo-rosettes, seen here, characterized by radially arranged tumor cells around a blood vessel core. https://youtu.be/UXDIYV_yMro

The brain of a premature fetus, shown here (front of brain pointing to the left) is initially smooth in the early stages of development. After about 20 weeks gestation, grooves develop in the cortical surface that gradually become more defined until they form well delineated gyri and sulci (i.e. bumps and grooves) typical of a mature brain. The brain... Continue Reading →

A common histologic finding in ependymomas (shown here) are perivascular pseudo-rosettes characterized by neoplastic ependymal cell nuclei radiating outward from a blood vessel, which creates a pink zone of glial processes immediately surrounding the blood vessels.
