Group A streptococcal septicemia with retropharyngeal abscess: a case report

Group A streptococcal (GAS) septicemia is rare in occurrence but has a significant morbidity and mortality, whereas retropharyngeal abscess (RPA) is infrequent and it is most commonly found in children under the age of 6 years, with half of the cases occurring in children between 6 and 12 months old. This report concerns a case of GAS septicemia complicated with RPA. The patient, a five-year-old boy, was referred from a local medical department under the impression of meningitis. However, blood and throat cultures were both found to be positive for group A streptococci. Widening of the retropharyngeal space was noted in lateral neck roentgenography. RPA was confirmed by computed tomography (CT) of the neck. Ampicillin was prescribed for a period of four weeks. The patient was then discharged and oral form ampicillin was continued for four more weeks. No surgical incision and drainage was performed. Complete disappearance of the abscesses were noted via CT of the neck at an Outpatient Department follow-up.
