Bilophila wadsworthiain brain abscess: case report.

Area of Science:

• Otolaryngology
• Neurosurgery
• Infectious Diseases

Background:

• Chronic otitis media and cholesteatoma can lead to serious intracranial complications.
• Brain abscesses are rare but life-threatening consequences of middle ear infections.

Purpose of the Study:

• To report a unique case of brain abscess secondary to chronic otitis media with cholesteatoma.
• To document the microbial findings, including the novel isolation of Bilophila wadsworthia.

Main Methods:

• A patient with a history of chronic otitis media and cholesteatoma presented with symptoms of a brain abscess.
• Computed tomography (CT) scan with contrast identified abscess cavities in the cerebellum.
• Microbiological cultures were performed on cholesteatoma and abscess pus samples.
• Surgical intervention (craniotomy) and antimicrobial therapy were administered.

Main Results:

• Cultures from cholesteatoma and brain abscess pus revealed significant growth of anaerobic bacteria, including Bilophila wadsworthia, Bacteroides fragilis, and Prevotella oris.
• Bilophila wadsworthia was isolated for the first time in association with chronic otitis media and brain abscess.
• The patient experienced a complete cure and total recovery following craniotomy and a course of antibiotics (penicillin plus metronidazole, later augmentin).

Conclusions:

• This case underscores the potential for severe intracranial infections stemming from chronic otitis media and cholesteatoma.
• The identification of Bilophila wadsworthia in this context expands our understanding of the polymicrobial nature of these infections.
• Effective management involves a combination of surgical debridement and appropriate antimicrobial therapy targeting anaerobic pathogens.
