颅内感染可能由邻近引起，例如乳突炎或急性中耳炎，或由感染源的血行传播引起。星座链球菌是一种来自正常生殖器、口腔和胃肠道菌群的球菌，有形成脓肿的倾向，但不会引起感染性心内膜炎 (IE)。此外，星座链球菌是一种极其罕见的脑脓肿病原体。我们报告了一名患有结直肠肿瘤的女性的病例，她因星座链球菌菌血症而出现 IE 和小脑脓肿。
Intracranial infections may result from contiguity, such as mastoiditis or acute otitis media, or from haematogenous dissemination from an infectious source. Streptococcus constellatus, a coccus from the normal genital, oral and gastrointestinal flora, has a tendency to form abscesses, but not to cause infective endocarditis (IE). Also, S. constellatus is an extremely rare causative agent of brain abscess. We report the case of a woman with a colorectal tumour who presented with IE and cerebellar abscesses due to a S. constellatus bacteraemia.
