Sonographic patterns of the gallbladder in acute viral hepatitis

Ultrasound was used for a serial evaluation of gallbladder modifications in 61 patients with acute viral hepatitis during both the acute phase of the illness and recovery. Most of the patients studied within 7 days from the onset of symptoms and/or jaundice showed sonographic abnormalities of the gallbladder (increased wall thickness, reduced volume, abnormal bile content). A normal ultrasound pattern of the gallbladder was progressively restored during the clinical recovery in most of the patients. A statistical correlation was found between the gallbladder wall thickness and the alanine transferase index.
