“Gallbladder Stones with CBD Stones — Cholelithiasis & Choledocholithiasis on Ultrasound”

Описание: “CBD Stone Without IHBR Dilatation — Important Teaching Case”

Not all CBD stones cause upstream dilatation.

• Small or non-impacted stones may not obstruct continuously
• Early choledocholithiasis can appear before IHBR dilatation develops
• Intermittent stone movement can decompress the biliary system

This ultrasound case demonstrates Cholelithiasis with Choledocholithiasis — showing multiple gallbladder stones along with echogenic calculi visualized within the common bile duct (CBD), producing posterior acoustic shadowing.

On B-mode ultrasound, the gallbladder shows multiple echogenic calculi with clean acoustic shadows, consistent with gallbladder stones. The CBD is visualized with intraluminal echogenic foci, confirming CBD stones (choledocholithiasis).

This case highlights important ultrasound features used to differentiate:
• Gallbladder calculi
• CBD calculi
• Biliary obstruction patterns
• With & without IHBR dilatation

This video is useful for:
• Radiology residents
• Sonography students
• Ultrasound practitioners
• Medical educators
• Biliary imaging learners

✔ Posterior acoustic shadowing — classic stone sign
✔ CBD stones may occur with or without IHBR dilatation
✔ Always assess
• porta hepatis
• CBD diameter
• intrahepatic biliary radicals
✔ Correlate with LFTs & clinical presentation

Recommended next-step imaging may include MRCP / ERCP where clinically indicated.
