Calcification
Many intra-abdominal structures may calcify and become visible on plain x-ray. Some are of little significance, such as costal cartilages, phleboliths, mesenteric lymph nodes and distal blood vessels.
Others of more significance include:
- Renal calculi (90% radio opaque) (Fig 1)
- Gallstones (10% radio opaque) (Fig 2)
- Pancreas in chronic pancreatitis
- Abdominal aortic aneurysm (AAA) (Fig 3)
- Fibroids (Fig 4)
- Prostate
- Appendicolith
