Case #33


Findings

  • Gallbladder is visualized but is decompressed
  • Branching linear echogenic foci throughout the liver with a peripheral predominance
  • Liver is otherwise normal in size and appearance
  • No intrahepatic or extrahepatic biliary duct dilation
  • Increased right renal cortical echogenicity without hydronephrosis or focal mass
  • Echogenic, thickening bowel wall in the right upper quadrant
  • Visualized portions of the pancreas and aorta are normal in appearance


Diagnosis

Pneumatosis and portal venous gas

Sample Report

Branching linear echogenic foci throughout the liver with a peripheral predominance, concerning for portal venous gas. Thickened, echogenic bowel wall in the right upper quadrant, concerning for pneumatosis. Together, these findings are highly concerning for bowel ischemia. Recommend surgery consultation.

Gallbladder is visualized but is decompressed. These findings are not consistent with biliary atresia.

Liver is otherwise normal in size and appearance with no biliary duct dilation.

Increased right renal cortical echogenicity, which can be seen with medical renal disease. No hydronephrosis.

Images

Multiple punctate and linear echogenic foci throughout the liver (red arrows), concerning for portal venous gas. Thickened, echogenic adjacent bowel wall (yellow arrow) with ill-defined posterior acoustic shadowing (blue arrows), concerning for pneumatosis.
