Abstract

Abstract: Brain abscess remains a life-threatening condition. Here, we are reporting a case of brain abscess due to Bacteroides thetaiotaomicron in a previously known case of recurrent otitis media. A 15 years old boy with a history of recurrent otitis media presented with the complaints of right otalgia, headache and fever. Computed Tomography (CT) brain and neck revealed fluid filled right middle ear cavity with bony destruction along the inner cortex of right temporal bone. The abscess was drained and culture showed growth of Bacteroides thetaiotaomicron. This report illustrates the importance of MALDI-TOF MS in the species level identification of anaerobes thereby facilitating the selection of appropriate and prompt adjuvant antibiotic therapy. This timely identification thus led to a favourable outcome in an era of increasing antimicrobial resistance. Highlights: B. thetaiotaomicron resistant to metronidazole and carbapenem is an alarming situation and poses a threat for severe infections. This report illustrates the importance of considering anaerobes as the cause of brain abscess and highlights the usefulness of MALDI to species level identification. IMALDI provides result with a decreased turnaround time of 2 days which facilitates appropriate treatment.
