Acute Subdural Abscess due to Mixed Infection of Eikenella corrodens and Streptococcus constellatus

Cultures of paronychia of the fingers have grown aerobic and anaerobic bacteria. Each was recovered individually in only about a quarter of the patients and a mixed aerobic/anaerobic flora was isolated in half of the patients. The predominant anaerobic organisms were Gram-positive anaerobic cocci, Bacteroides species and Fusobacterium species. The predominant aerobic organisms were Staphylococcus aureus, gamma-haemolytic streptococci, Eikenella corrodens, group A beta-hemolytic streptococci, alpha-hemolytic streptococci, and Klebsiella pneumoniae. Candida albicans was recovered in about 15% of the cases. The management of this infection is discussed.

Early Use

Torticollis in children can be a sign of a potentially dangerous disease; the correct diagnosis is not always obvious on history and physical examination. The use of point-of-care ultrasound (POCUS) helps to limit the differential diagnosis and direct appropriate further laboratory and radiology-performed evaluation. We present a case of a 10-year-old child whose deep neck infection (DNI) was timely diagnosed in the paediatric emergency department by early use of POCUS and drained under POCUS guidance after admission to the hospital. The culture from the fluid grew Eikenella corrodens, Streptococcus constellatus and Prevotella buccae. This case demonstrates that DNIs occur in children with acute acquired torticollis, even without fever and demonstrates the importance of early use of POCUS in cases where DNI is a potential diagnosis. Moreover, this case emphasises the importance of microbiological identification of DNIs that can be the key to successful treatment.
