Clinical manifestations of liver abscess are high fever, chills, persistent dull pain or distending pain in the liver area, nausea, malaise and so on. The first choice of examination for liver abscess is ultrasonography, which reveals a hypoechoic, round or ovoid, well-defined lesion in the liver region.
