Abstract:
Objective To observe the clinical and imaging features of invasive Klebsiella pneumoniae liver abscess syndrome(IKPLAS).Methods Data of 68 patients with Klebsiella pneumoniae liver abscess(KPLA)were retrospectively analyzed.The patients were divided into IKPLAS group(n=25)or non-IKPLAS group(n=43)according to extrahepatic invasive infection or not.Clinical data as well as CT and/or MRI findings were compared between groups.Results The patients'age was lower,while glycated hemoglobin and D-dimer levels were higher in IKPLAS group than those in non-IKPLAS group(all P＜0.05).Hepatic venous thrombophlebitis was detected in 18 cases in IKPLAS group and 6 cases in non-IKPLAS group,while arterial phase abnormal high perfusion around abscess was noticed in 10 cases in IKPLAS group and 28 cases in non-IKPLAS group,both being significantly different between groups(both P＜0.05).The extrahepatic infection in IKPLAS group mainly observed in lungs(19/25,76.00%).Conclusion The ages were lower,while glycated hemoglobin and D-dimer levels were both higher in IKPLAS than in the other KPLA patients.Often appeared hepatic venous thrombophlebitis and extrahepatic infection mainly affecting lungs were imaging characteristics of IKPLAS.
