Rib notching

大動脈縮窄
上大静脈症候群
neurofibromatosis

高安動脈炎でも見られるってどっかで聞いたような気がするが・・・

Notching of the ribs has many origins. Basically, any of the three major intercostal structures can enlarge, compress, and erode the lower borders of the ribs, producing areas of notching. They are intercostal arteries, veins, and nerves. Coarctation of the aorta7 (see Fig. 15–1A) represents the most common cause of rib notching as a result of dynamic dilatation and tortuosity of the arteries. Superior vena cava syndrome can cause a similar phenomenon of venous origin. Neurofibromatosis also can produce rib notching by numerous intercostal tumors.
