The ultrasound image shows an anechoic (black) fluid collection in the perihepatic and perirenal spaces. The fluid outlines the liver (LIV) and right kidney (RK), which is characteristic of free fluid in the peritoneal cavity — consistent with ascites.

Sonographic features of ascites:

Anechoic (or hypoechoic) fluid in dependent areas of the abdomen

Seen surrounding the liver, spleen, and intestines

Can be free-flowing or loculated

Bowel loops may be floating or displaced centrally

This image is consistent with a typical finding of ascites: free fluid in Morison’s pouch (hepatorenal recess), a common site for fluid accumulation.

Differentiation from other options:

A. Hydropic gallbladder: Refers to an enlarged gallbladder filled with clear bile; not visible in this image.

B. Hemoperitoneum: May appear similar to ascites, but usually has complex echogenicity or layering if acute; clinical context (trauma, bleeding) is essential for diagnosis.

C. Bowel obstruction: Would show dilated, fluid-filled bowel loops with peristalsis or to-and-fro motion, not evident here.
