Case Report of Pediatric Osteomyelitis: A Double Whammy of Unusual Etiology and Antibiotic Susceptibility.

INTRODUCTION: Osteomyelitis is one of the infrequent presentations of Salmonella infection. Most of the case reports are among adult patients. It is very rare in children, and is most often associated with hemoglobinopathies or other predisposing clinical conditions.

CASE REPORT: In this article, we present a case of osteomyelitis caused by Salmonella enterica serovar Kentucky, in a previously healthy 8-year-old child. Further, this isolate had an unusual susceptibility pattern; it showed resistance to the third-generation cephalosporins, akin to ESBL production among Enterobacterales.

CONCLUSION: Osteomyelitis caused by Salmonella does not have any specific clinical or radiological features, both in adult and pediatric age groups. A high index of suspicion, using appropriate testing methodologies and awareness about emerging drug resistance helps in accurate clinical management.
