A rare case of hypervirulent Klebsiella pneumoniae liver abscess and bacterial endophthalmitis associated with distal bile duct cancer.

We report a case of a patient with distal bile duct cancer who presented with ocular pain and eye redness due to a liver abscess. The patient developed a liver abscess while waiting for surgery. Since Klebsiella pneumoniae with high viscosity was identified and imaging studies showed systemic infection, a diagnosis of klebsiella invasive syndrome was made. In addition, infectious intraocular inflammation was also observed at the same time. In addition to antibiotic therapy, vitrectomy and percutaneous transhepatic abscess drainage successfully normalized the inflammatory response and negative blood cultures were obtained. Thirty-four days after the start of treatment, surgery was performed and the postoperative course was uneventful, and the patient was discharged from the hospital on the 39th postoperative day. Forty-six months after that surgery, there has been no evidence of recurrence of cholangiocarcinoma or recurrence of infection, but unfortunately, vision loss in the right eye remains. Some Klebsiella pneumoniae are highly pathogenic and are often reported from Southeast Asia, and ocular pain and hyperemic symptoms are important physical findings.
