Salmonella-Related Septic Arthritis in an Immunocompetent Adult: A Case Report.

Salmonella is a well-known cause of foodborne illness, commonly resulting in gastroenteritis, bacteremia, and focal infections. Salmonella septic arthritis is a rare entity with cases mostly prevalent in patients with sickle cell disease, immunocompromised state, and advanced age. Here, we present a case of Salmonella septic arthritis in a previously healthy young gentleman with no risk factors who presented with fever, skin rash, abdominal pain, and left hip pain. Initial laboratory findings showed high inflammatory markers and negative blood culture. MRI of the left hip joint showed effusion and features of inflammatory changes. The diagnosis was confirmed by joint aspirate culture growing Salmonella B. Furthermore, he underwent joint arthrotomy; pus was drained and treated with an antibiotic. Subsequently, the patient responded to treatment with marked clinical recovery.
