Figure 1. (a) On day 1 after admission, abdominal computed tomography with intravenous contrast showed no gallbladder stone. (b) On day 5 after admission, plain abdominal computed tomography showed a high-density lesion in the gallbladder, indicative of ceftriaxone-associated pseudolithiasis. (c, d) On day 22 after admission, abdominal computed tomography with intravenous contrast showed a high-density biliary sludge pattern and iodinated contrast material extravasation into the gallbladder (arrow).
Figure 2. (a, b) The autopsy revealed gallbladder rupture, resulting in a massive hematoma. (c) Final pathology demonstrated hemorrhagic and necrotic changes with focal neutrophilic cell infiltration and fresh thrombi (hematoxylin-eosin staining ×400).
