Rare septic arthritis of the wrist and carpus primary osteoarticular manifestation of Mycobacterium tuberculosis: A case report

Abstract

Mycobacterium tuberculosis is one of the oldest and most studied infections, yet it remains one of the most common causes of infection-related death worldwide. The majority concern pulmonary tuberculosis. Therefore, extrapulmonary cases are rare and are often neglected in the differential diagnosis, especially in chronic musculoskeletal complaints. Nevertheless, osteoarticular manifestation of tuberculosis can cause disabling destruction of bone, cartilage, and surrounding soft tissues which may be exacerbated by a delay in diagnosis. This case report documents a case of primary osteoarticular tuberculosis causing septic arthritis of the wrist and carpus. In our case, the patient had no pulmonary burden of tuberculosis, which further delayed diagnosis and lead to irreversible damage to the wrist as well as carpus. This case illustrates the need to consider this diagnosis in at risk populations in order to prevent a delay in diagnosis and treatment.
