Thirty-seven years old male patient with non-Hodgkin lymphoma seeking for abdominal ultrasound to exclude abdominal lymphomatous infiltration. Imaging findings: grey scale B-mode ultrasonography (a): normal sized liver with an ill-defined hypoechoic focal lesion seen in segment VII measuring 3.1 × 2.3 cm with 5.4 cm depth from the skin. ϖ Color-coded shear wave sono-elastography: the lesion showed yellow green color (b, c, d), while the liver parenchyma showed dark blue color (e, f, g). ϖ Shear wave sono-elastography stiffness values of the focal lesion: E1 = 14.27 kPa (b), E2 = 14.51 kPa (c), and E3 = 13.34 kPa (d). Calculated average stiffness value of the lesion = 14.04 kPa. ϖ Shear wave sono-elastography stiffness values of the parenchyma (e, f, g): E1 = 4.38 kPa (e), E2 = 5.36 kPa (f), and E3 = 4.80 kPa (g). Calculated average stiffness value of the parenchyma = 4.84 kPa. • Lesion/parenchyma stiffness ratio = 2.90. ϖ Axial contrast enhanced CT study (non-contrast (h), post contrast (i)): normal size liver with a well-defined hypodense focal lesion seen in segment VII showed faint peripheral enhancement. ϖ Pathology: lymphoma. ϖ Diagnosis: hepatic lymphomatous infiltration
