The liver spans multiple regions because it is a large organ that lies under the right to midline under the diaphragmatic dome and extends across the upper abdomen. The right lobe sits predominantly beneath the right costal margin, placing much of the liver in the right hypochondrium. Its superior surface lies high in the epigastric region, covering a substantial portion there. The left lobe extends across the midline into the left hypochondrium, so part of the liver is felt or seen there as well. Taken together, the liver occupies the right hypochondrium, much of the epigastric region, and a portion of the left hypochondrium, making the option “All of the above” the best choice.
