Intrauterine device infection causing concomitant streptococcal toxic shock syndrome and pelvic abscess with Actinomyces odontolyticus bacteraemia.

Intrauterine devices (IUDs) are rarely associated with serious infections. We report an unusual concomitant infection of group A Streptococcus (GAS) causing toxic shock syndrome and pelvic abscess with Actinomyces odontolyticus associated with an IUD in a healthy 50-year-old patient. The IUD was subsequently removed and the patient recovered on the appropriate antibiotics. This case highlights the importance of clinicians' high index of suspicion of an IUD infection and prompt removal of the infected foreign body to obtain source control. 2016 BMJ Publishing Group Ltd.
