Cerebellar abscesses, infective endocarditis and bacteraemia due to a rare pathogen: Streptococcus constellatus

Rafael García Carretero. BMJ Case Rep. .

Abstract

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.

Figure 1
Slides of the brain MRI show two cerebellar lesions (arrows): one in the left middle cerebellar peduncle (1.8 cm in size) and one in the left lateral hemisphere (3.5 cm in size). Both lesions were hypointense in T1 (not shown), hyperintense in T2 and were surrounded by vasogenic oedema. (A) Transversal plane. (B) Coronal plane.

Lumen of the sigmoid colon was partially obstructed by a rectal mass located 18 cm above the dental line, and its surface was uneven and haemorrhagic (arrow).
