Gallbladder pseudolithiasis induced by cephalosporin

Case contributed by Dr Maulik S Patel


The patient was on a drug from the cephalosporin class prior to performance of the USG.

Patient Data

Age: 7 years
Gender: Male

US at presentation

The gallbladder is contracted with an edematous wall. There are echogenic foci in the gallbladder lumen without posterior acoustic shadowing. 


Ultrasound one week after discontinuation of the antimicrobial agent

The gallbladder is distended with normal wall thickness. It shows anechoic lumen.

Case Discussion

A child with fever had an ultrasound. The USG showed sludge in the gallbladder. The patient was on a cephalosporin-class agent pre-USG.

Follow up ultrasound one week after discontinuation of the agent showed the absence of gall bladder sludge/pseudolithiasis.
