, a (HACEK) organism, is commonly found in the oropharynx. Although it rarely causes endocarditis, it can pose a significant risk to young children. We report a case of endocarditis in a previously healthy 15-month-old male who initially presented with symptoms of an upper respiratory infection. Blood cultures taken at 60 hours revealed the presence of . Subsequent echocardiogram and brain MRI demonstrated large vegetation on the mitral valve and septic emboli in the right occipital and left posterior parietal lobes. The patient was treated with intravenous ceftriaxone and underwent mitral valve repair with annuloplasty. This case illustrates the presentation of endocarditis with initial respiratory symptoms and the subsequent identification of the infection through blood cultures and imaging. For pediatric patients presenting with upper respiratory symptoms, there may be clinical benefit to noninvasive ultrasound imaging to help rule out atypical pathologies like endocarditis.
一种HACEK微生物通常存在于口咽中。虽然它很少引起心内膜炎，但对幼儿可能构成重大风险。我们报告一例先前健康的15个月大男性的心内膜炎病例，该患儿最初表现为上呼吸道感染症状。60小时采集的血培养显示存在该微生物。随后的超声心动图和脑部MRI显示二尖瓣上有大量赘生物，右枕叶和左顶叶后部有脓毒性栓子。患者接受了静脉注射头孢曲松治疗，并进行了二尖瓣瓣环成形术修复。该病例说明了以初始呼吸道症状表现的心内膜炎以及随后通过血培养和影像学确定感染情况。对于出现上呼吸道症状的儿科患者，无创超声成像可能有助于排除心内膜炎等非典型病症，具有临床益处。
