title: Primary musculoskeletal mycobacterium infection with large cystic masses after total hip arthroplasty.
abstract: Primary mycobacterial infections in the musculoskeletal system are rare with a limited number of published case reports. This report describes a case involving a primary musculoskeletal tuberculous abscess. A 62-year-old male patient who had a right total hip arthroplasty performed 8 years earlier, using metal-on-metal articulation presented with a 1-year history of non-tender masses on his right thigh. Initially, it was assumed he had metallosis. Intraoperatively, an incision into the mass was conducted which resulted in draining of a whitish-grey pus like fluid. A diagnosis of tuberculosis was confirmed with both microscopic and histological examination. The patient was treated over a course of six months with an anti-tuberculosis medication regimen following the confirmation of a solitary soft tissue tuberculosis infection. At the 24 month follow-up, the patient was asymptomatic with no relapse of the mass.
