Incidental Findings on Abdominal CT
Abdominal CT examinations usually cover the entire abdomen and pelvis, including all organs and tissues in the intraperitoneal, retroperitoneal, extraperitoneal/pelvic spaces, as well as the extra-abdominal soft tissues; bony structures of the spine, sacrum, pelvis, and hips; and lower part of the chest including parts of the lungs and pleural spaces. The multitude of organs and tissues involved makes abdominal CT reading complex and allows for a multitude of incidental findings that may be of degenerative, neoplastic, or other etiologies. Although scanning is sometimes limited to only the “abdomen” or only the “pelvis,” “abdominal CT” in this chapter refers to abdominal-pelvic CT, i.e., both compartments.
