There are many tests that may be done to confirm a liver injury; the most common is a computerized tomogram, or CT scan, of the abdomen. This is a diagnostic procedure that uses a combination of X-rays and computer technology to produce cross-sectional images both horizontally and vertically of the body. A CT scan shows detailed images of any part of the body. It not only shows whether or not the liver is injured, but may say how badly it's injured and if any other internal injuries are present.
Liver injuries may be diagnosed in different ways. Most children with liver injuries have pain in the upper right part of their abdomen, their right back, or on top of their right shoulder. Pressing on or under the right ribs may hurt. With a severe liver injury the child may feel lightheaded, be pale, or have a weak pulse, all findings related to internal bleeding. Children who might have a liver injury should be evaluated immediately by a doctor.
