[Pseudolithiasis caused by ceftriaxone in children: a case report].

Recently, there are in literature some reports concerning the sonographic observation of transient gallbladder precipitates in children and adults during ceftriaxone treatment. The condition is defined as ceftriaxone-reversible "pseudolithiasis" and the gallbladder precipitates resolve spontaneously after cessation of therapy. We present a case of a 1 year old children treated with ceftriaxone who presented asymptomatic pseudolithiasis that resolved partially two weeks after cessation of treatment. The sonographic observation performed four months after cessation of therapy show a normally gallbladder, without precipitates or sludge.
