is a Gram-positive commensal of the oral cavity with tendency to cause brain and liver abscesses. Mediastinal involvement from is very rare. We present a case of 22-year-old male with newly detected mediastinal conglomerate nodal mass. On his way for bronchoscopy, he developed seizures and was found to have three brain lesions. The aspirate from brain biopsy grew whereas the aspirate from mediastinum showed only acute inflammation. Follow up imaging after antibiotic treatment showed interval resolution of brain abscesses and the mediastinal mass. We believe that the patient had aspiration pneumonia from which then metastasized to mediastinum and brain. Our aim is to make physicians aware of this unusual presentation of infection as a mediastinal mass. A strong effort should be made to isolate the organism from the involved body sites and fluid cavities to confirm the diagnosis.
是口腔革兰氏阳性共生菌,有引发脑和肝脓肿的倾向。其导致纵隔受累极为罕见。我们报告一例22岁男性,新发现纵隔融合性结节肿块。在其接受支气管镜检查途中,出现癫痫发作,发现有三处脑病变。脑活检吸出物培养出该菌,而纵隔吸出物仅显示急性炎症。抗生素治疗后的随访影像显示脑脓肿和纵隔肿块有间隔期消退。我们认为该患者因该菌发生吸入性肺炎,继而转移至纵隔和脑部。我们的目的是让医生了解这种作为纵隔肿块的该菌感染的不寻常表现。应大力从受累身体部位和体腔中分离出该病原体以确诊。
