Even though Gemella morbillorum infection (GMI) is rare in humans, it may nevertheless, cause endocarditis, meningitis, brain abscess, pleural empyema, nephritis, mediastinitis, and--occasionally--liver abscess. We are describing the case of a 64-years-old Caucasian male admitted with fever and abdominal pain. Laboratory parameters revealed inflammation signs, and instrumental examinations showed the presence of diverticula in the ascending colon. Abdominal ultrasound (US) and computer tomography (CT) showed two focal lesions in the right liver lobe. One had the characteristics of a simple cyst; the second was hypoechoic with a low density area, possibly containing necrotic material. US-guided needle biopsy was found negative for neoplastic cells, showing purulent infiltrate. Pus culture was found positive for GMI. Systemic antibiotic therapy coupled with repeated US-guided needle aspiration, induced the resolution of the hepatic abscess. Few cases have been reported of hepatic abscess caused by GMI in immunocompetent non-cirrhotic subjects.
尽管麻疹孪生球菌感染（GMI）在人类中较为罕见，但它仍可能导致心内膜炎、脑膜炎、脑脓肿、胸膜脓胸、肾炎、纵隔炎，偶尔还会引发肝脓肿。我们正在描述一名64岁白种男性因发热和腹痛入院的病例。实验室检查参数显示有炎症迹象，仪器检查显示升结肠存在憩室。腹部超声（US）和计算机断层扫描（CT）显示右肝叶有两个局灶性病变。一个具有单纯囊肿的特征；另一个为低回声，有低密度区，可能含有坏死物质。超声引导下针吸活检未发现肿瘤细胞，显示为脓性浸润。脓液培养发现GMI呈阳性。全身抗生素治疗结合反复超声引导下针吸，促使肝脓肿消退。在免疫功能正常的非肝硬化受试者中，由GMI引起肝脓肿的病例报道较少。
