Normally, the liver is not palpable under the rib cage, but in people with a flabby abdominal wall and a thin body type, the lower edge of the liver can be palpated under the rib cage during deep inspiration, but within 1 cm. At this point, the liver is generally soft and there are no symptoms of pressure pain. If the liver is hard when pressed, it is likely to be an enlarged liver. The disease that causes the hard texture of the liver may be cirrhosis or liver tumor, especially primary liver cancer. In this case, the edges of the liver are sharper and the margins are not uniform in thickness, and multiple nodules or more obvious masses of varying sizes may be palpable, and the patient may also have more obvious symptoms of pressure pain. If abnormalities are found during clinical examination, further liver imaging can be performed, the most commonly used one is liver ultrasound, which is very effective for preliminary determination of liver lesions, and if necessary, enhanced CT or MRI is also needed to determine the nature of liver nodules or masses.
