A forum dedicated to the expansion in neuropathology knowledge for students and practitioners alike.
Metastatic cancers (i.e. cancers that originate somewhere else and travel to the brain usually via the bloodstream) can occur singly or, as pictured here, as multiple lesions. Sometimes brain metastases represent the initial clue that the person has cancer somewhere else in the body, as was the case for this patient who was found to have three enhancing cerebral lesions...

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 →
