Four cases of ceftriaxone-associated biliary pseudolithiasis

Abstract

We report four cases of ceftriaxone-associated biliary pseudolithiasis. All cases were treated conservatively without cholecystectomy or endoscopic retrograde cholangiopancreatography. Because conservative treatment is the preferred treatment, clinicians should be aware that biliary pseudolithiasis is possible in patients who have abdominal pain associated with gallbladder stones on imaging. Regardless of whether we are treating adults or children, it is necessary to check for a history of ceftriaxone treatment before symptom onset.
