Figure 1: Ultrasound scans showing features of gallbladder sludge in Cases 1–4. Ultrasound on 4th day of ceftriaxone usage, using an ’Apogee Ultrasound machine, 1991 Model’ with a 5 MHz convex linear array transducer. The gallbladder, intra/extra-hepatic bile ducts and liver were examined methodically. Abnormal gallbladder sonographic findings were reported as biliary sludge accumulation (arrows in Cases 1 and 2) if there was low-amplitude echo within the lumen with no post-acoustic shadows |
