I read your question. Echogenicity is the ability to create an echo, i.e. return a signal in ultrasound examinations. Increased echogenicity of the liver usually means that there is fatty infiltration in parts of the liver. In certain causes a focal area of increased echogenicity would indicate a discrete mass.
At US, the fetal lungs normally appear homogeneous and are slightly more echogenic than the liver (Fig 1; see also Fig E3 [online]). The echogenicity of the lung increases as gestation advances. The presence of cysts or focal increased echogenicity of the lung parenchyma indicates a mass.
