Disseminated Gonococcal Infection Presenting as Isolated Septic Arthritis: A Case Report and Review of Literature

Neisseria gonorrhoeae is a gram-negative diplococcus that passes from one person to another through sexual contact. On rare occasions, Neisseria gonorrhoeae may spread from the primary mucosal site to distant parts of the body and present with signs of systemic illness; this is commonly known as disseminated gonococcal infection (DGI). We present a case report of an 18-year-old patient who was diagnosed with septic arthritis of the right third metacarpophalangeal (MCP) joint without mucosal involvement or systemic symptoms and who was found to have gonococcal bacteremia. This case highlights the importance of clinician awareness of the many extragenital manifestations of DGI and a high index of suspicion in the setting of septic arthritis and high-risk sexual practices. Diagnosing DGI early and providing prompt treatment may prevent complications of sepsis, joint destruction, and a prolonged hospital stay.
