Tuberculous synovitis in a HIV positive patient.

Tuberculosis of the appendicular skeleton is an uncommon infection by tubercle bacilli. Thirty percent of the skeletal tuberculosis involves joints, the knee being the third most common joint affected. We report a case of tubercular synovitis of the knee joint in a 30-year-old HIV seropositive male. The diagnosis was done by Ziehl-Neelsen stain and culture on Lowenstein Jensen medium, of the synovial fluid along with the X-ray findings of the knee joint. The X-ray of the chest showed findings suggestive of pulmonary tuberculosis. The patient was responding well to the antitubercular treatment at the last follow up.
