Intrahepatic bile duct stones B-ultrasound manifestations
Intrahepatic bile duct stones show typical sonographic changes on ultrasound, appearing as punctate or mass-like strong echoes within the liver, accompanied by acoustic shadows. These strong echoes are distributed along the intrahepatic bile ducts. The bile duct proximal to the stone may exhibit varying degrees of dilation, and the dilated intrahepatic bile duct, along with the accompanying portal vein, forms a parallel tube sign. Around the strong echoes of the stones, a narrow anechoic region can be seen encircling them, and the stones generally do not move with changes in body position. Intrahepatic bile duct stones can also cause thickening of hepatic parenchyma echoes and internal echo heterogeneity.
Can cirrhosis be detected by a CT scan?
Cirrhosis can be detected by a CT scan. Early-stage cirrhosis has no specific diagnostic value on CT, but middle to late-stage cirrhosis typically manifests as wavy changes in the liver capsule, enlarged liver lobes, and disproportionate size of liver lobes, with most changes involving an enlargement of the left lobe and caudate lobe and a relative shrinkage of the right lobe. Additionally, secondary manifestations of cirrhosis, such as portal hypertension, can cause enlargement of the spleen and varices in the lower esophagus and stomach fundus. When cirrhosis is detected, it is advisable to perform an enhanced CT scan to determine the potential for malignant transformation in liver regenerative nodules.
