A rare case of invasive non-typeable Haemophilus influenzae spondylodiscitis and periprosthetic joint infection.

Abstract

A non-typeable Haemophilus influenzae (NTHi) was responsible for an invasive infection including bacteremia, spondylodiscitis with epidural abscess, and periprosthetic hip infection in a 79-year-old woman, triggered by a superinfected ethmo-orbital mucocele. Surgical drainage and antibiotic therapy allowed recovery. PET-scan full cartography of NTHi infection dissemination enabled the discovery of spondylodiscitis. This rare cause of spondylodiscitis and periprosthetic joint infection suggests a complete work-up is unavoidable.
