Asymptomatic pyogenic liver abscesses secondary to Fusobacterium nucleatum and Streptococcus vestibularis in an immunocompetent patient.

A 66-year-old male patient presented with symptoms and signs of L4/5 radiculopathy. He was found to be anaemic with elevated inflammatory markers and deranged hepatic enzymes. Imaging revealed lumbar canal stenosis and the presence of pyogenic liver abscesses from which Fusobacterium nucleatum and Streptococcus vestibularis were isolated. The hepatic abscesses were attributed to asymptomatic diverticular perforation. Multiple coexisting incidental infections were discovered, including oesophageal candidiasis, Helicobacter pylori, stool cultures positive for Strongyloides stercoralis, and sputum cultures positive for Enterobacter cloacae, Escherichia coli and Mycobacterium avium Extensive investigations for possible underlying immunosuppression were negative. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.
