Pyogenic liver abscess complicated with endogenous endophthalmitis caused by Klebsiella pneumoniae: A case report and Literature Review

Abstract

AbstractObjectivePyogenic liver abscess (PLA) is a common surgical infectious disease caused by various pathogens. Klebsiella pneumoniae is a relatively recent cause, often affecting patients with low immunity. Endogenous endophthalmitis (EE), a rare and serious complication of PLA, may appear with eye symptoms before PLA. By reviewing a case of Klebsiella pneumoniae‐induced PLA complicated with EE, we want to summarize the information about the characteristics, causes, and complications of PLA based on the literature review.MethodsThis case report describes a 37‐year‐old male who had fever high to 39°C for 10 days experienced blurred vision followed by nonlight perception vision. He reported a history of diabetes irregularly taking oral medications and insulin therapy. Imaging examination found a large low‐density area in the right lobe of the liver with an unclear border and vague surrounding fat gap. The blood culture was not positive. The culture of the drainage fluid from the liver puncture showed Klebsiella pneumonia. Blood and liver puncture drainage fluid were sent for microbial high‐throughput gene detection with next‐generation sequencing technology (NGS), which confirmed the diagnosis of Klebsiella pneumoniae‐induced PLA complicated with EE.ResultsThe patient's surgical incision had healed well at discharge, and he could feel light at his left eye. But the patient was lost to follow‐up since the third month after discharge.ConclusionBy reviewing this case and summarize the information about the characteristics, causes, and complications of PLA based on the literature review, we concluded that it is necessary to promptly perform liver puncture drainage and empirically use antibiotics for patients with PLA, especially those with poor glycemic control, to avoid serious complications such as EE.
