A forum dedicated to the expansion in neuropathology knowledge for students and practitioners alike.
The cerebral hemispheres are supplied with blood via three major arteries: the anterior, middle, and posterior cerebral arteries. This coronal section through the frontal lobes shows hemorrhage involving the vascular territory of which of these three major cerebral arteries? Answer: The cerebral hemispheres are supplied with blood via three major arteries: the anterior, middle, and posterior... Continue Reading →
Acute traumatic brain injury (TBI) can result in a variety of hemorrhagic cerebral insults leading to brain death. This photograph depicting a brain of a person involved in a motor vehicle accident, shows a large hemorrhage in the left temporal-occipital region that 1. involves the brain tissue proper (i.e. intraparenchymal hemorrhage), 2. extends beneath the arachnoid layer of...

The massive intraparenchymal hemorrhage depicted in the autopsy specimen of a 60-year-old male patient is the result of hypertensive vasculopathy. Bleeding originated in penetrating vessels of the basal ganglia and extended into adjacent cerebral structures. The blood acts as a space-occupying lesion, resulting in uncal and subfalcine herniation with associated tissue destruction.
