General and Systemic Histopathology, C601&C602

The many malformed vascular
channels are quite evident in the picture to the left. These lesions
are apt to bleed, as the presence of this specimen in our study attests
to. No this is not a surgical specimen. See this slide with the virtual microscope. |

Here you will see many large and malformed blood vessels that have a "hybrid" wall structure. In some areas the wall resembles a vein and in others an artery. Look for an elastic interna. One would never expect to see vessels of this size with such peculiar wall structure within the brain. This represents a congenital deformity and can cause death at any age. The vessels are subject to leakage or rupture and this subject in fact died with an intracerebral hemorrhage. |
