Diagnosis Acute cholecystitis – US / CT/ correlation|
Grayscale ultrasound images (A, B) of the right upper abdomen demonstrate stones within the gallbladder lumen (black arrows), gallbladder wall thickening (4.4 mm, dotted arrows) and free pericholecystic fluid (FF and full white arrow). These findings (in addition to positive Murphy’s sign and distended common bile duct beyond 7 mm) are consistent with acute cholecystitis. Contrast enhanced CT of the abdomen (C) in the same patient demonstrates again pericholecystic fluid (black arrow), gallbladder wall thickening and a distended gallbladder, the shadowing stones on ultrasound are not radiopaque and barely identified in the gallbladder lumen. Incidental note is made of a malrotated right kidney (asterisk).
