Small Bowel Pathologies - Video Lesson

Welcome back. In this video, we'll be talking about small bowel pathologies that we can see in sectional imaging. The first pathology is what we call Crohn's disease. Kron's disease is idiopathic inflammation of the bowels. So idiopathic basically means that we don't understand what causes this inflammation. Sometimes the inflammation has a known cause. But in the case of Crohn's disease, we don't know what causes it. There's various philosophies on this, but fundamentally, it is idiopathic, which means we don't understand the basic cause of Crohn's disease. Crohn's disease primarily affects the small bowel, but it can actually affect any point in the gastrointestinal system. So what does Crohn's disease look like in sectional imaging? Usually Crohn's disease, if we image it in section imaging, we will use CT scanning, and it appears as thickening of the bow walls and is sometimes associated with what we call fat stranding. So the bowel walls are usually fairly thin. Inflammation causes the bowel wall
