Severe deep neck space infection caused by Eggerthia catenaformis

Area of Science:

• Otorhinolaryngology
• Head and Neck Surgery
• Infectious Diseases

Background:

• Deep neck space infections (D N S I) are serious conditions requiring prompt management.
• Eggerthia catenaformis is an uncommon pathogen associated with severe D N S I.

Observation:

• A 64-year-old woman presented with acute, rapidly progressing neck swelling, fever, and dysphagia.
• Clinical examination revealed submental swelling, trismus, and laryngeal inflammation.
• A contrast-enhanced CT scan identified extensive infection in the deep neck spaces with multiple abscesses.

Findings:

• The patient underwent emergent surgery for abscess drainage and received broad-spectrum antimicrobial therapy.
• Four separate pus aspirates yielded various oral commensals, with Eggerthia catenaformis consistently cultured from all samples.
• Three subsequent surgical procedures were necessary for adequate drainage, followed by 4 weeks of antimicrobial treatment.

Implications:

• This case highlights Eggerthia catenaformis as a potential cause of severe, multi-compartmental deep neck space infections.
• Aggressive surgical management combined with appropriate antimicrobial therapy is crucial for successful treatment outcomes.
• Early recognition and intervention are vital for preventing life-threatening complications associated with deep neck infections.
