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 →
Cerebral edema, or increased swelling in the brain, can occur as the result of numerous etiologies, such as infection, inflammation, metabolic derangement, or neoplastic processes. Typically the brain has an undulating contour featuring crests or bumps called gyri, and troughs or grooves, called sulci. The mass effect produced by cerebral edema results in pushing or...

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.
