CT features of KPLA. a, Contrast-enhanced CT showing a multilocular liver abscess. Pus bacterial culture and drug sensitivity results are indicative of KP (non-ESBL-producing). b, CT showing a liver abscess with visible gas in the abscess cavity. Bacterial culture and drug sensitivity results are indicative of KP (ESBL-producing). c, CT showing a unilocular liver abscess, while a venous-phase contrast-enhanced scan shows a right venous filling defect. Blood bacterial culture and drug sensitivity results are indicative of KP (non-ESBL-producing). CT, computed tomography; ESBL-producing KPLA, extended-spectrum β-lactamase–producing Klebsiella pneumoniae liver abscess
