Abstract
Enlargement of organs or other solid tissues usually presents as an abdominal mass. Often, abdominal masses in children are found by an unsuspected parent or by a physician during a routine examination. Most masses have no specific signs or symptoms. Abdominal masses in children require immediate attention. History and physical examination may provide clues to the diagnosis. Ultrasound examination is the most useful screening test in most cases and may identify the organ involved and clarify whether the mass is solid or cystic. CT may be necessary to make a more precise diagnosis, especially solid masses. MRI is occasionally is helpful for specific abnormalities.
