要約 背景:Klebsiella pneumoniaeによる肝膿瘍は,多臓器に転移性病変を形成しやすく,invasive liver abscess syndromeと呼ばれる。目的:眼内炎を契機に肝膿瘍が発見された症例の報告。症例:73歳女性が3週間前からの眼痛と眼瞼腫瘍で受診した。4日前に発熱と意識障害で精神科病院に入院し,抗生物質メロペネムの投与を受けた。糖尿病と統合失調症の既往があった。所見:39℃の発熱があり,右眼に光覚はなく,前房に強い炎症所見があった。超音波検査で硝子体混濁と網膜下膿瘍が疑われた。腹部の造影CTで肝膿瘍が発見された。白血球増加と血糖値の上昇があり,感染症に伴う播種性血管内凝固症候群(DIC)と診断された。内視鏡的胆管ドレナージでグラム陰性桿菌,肝膿瘍と硝子体からK. pneumoniaeが検出された。抗生物質などの投与で全身状態が改善し,初診から12日後に退院転科した。右眼視力は回復しなかった。結論:眼内炎を契機として肝膿瘍が発見された本症例は,典型的なinvasive liver abscess syndromeであったと診断される。眼科受診が遅く,失明が回避できなかった。
Abstract. Purpose:To report a case of liver abscess detected after onset of endophthalmitis. Case:A 73-year-old woman presented with pain and eyelid swelling in the right since 3 weeks before. She had been hospitalized and treated with systemic antibiotics since 4 days before. She had been suffering from diabetes mellitus and schizophrenia. Findings:Visual acuity was no light perception right. The right eye showed intense signs of inflammation in the anterior chamber. Echography showed findings suggestive of vitreous opacity and subretinal abscess. Computed tomography(CT)led to the diagnosis of liver abscess. She showed increased leukocytes and blood sugar level suggestive of disseminated intracascular coagulation syndrome(DIC). Endoscopic drainage of the bile, as well as aspirated specimen from liver abscess and the vitreous, showed Klebsiella pneumoniae. After improvement of systemic manifestations, she was referred to another hospital 12 days after her initial visit. Visual acuity in the right eye failed to improve. Conclusion:This patient was a typical case of invasive liver abscess syndrome due to K. pneumoniae. Visual outcome was unfavorable due to delayed recognition.
