Tuberculosis of the Wrist Accompanied with Calcium Pyrophosphate

抄録

This is a rare case of tuberculosis (TB) complicated with pseudogout of the wrist joint in a non-immunocompromised 84-year-old female with a history of pulmonary tuberculosis. She was diagnosed with extrapulmonary tuberculosis of the wrist based on a polymerase chain reaction (PCR) study and synovial fluid aspiration in which the cytology was positive for acid-fast bacilli. Calcium pyrophosphate was also positive. We must be careful not to miss articular tuberculosis as it may mimic common inflammatory arthritis, such as pseudogout of the wrist. Even if the patient is positive for calcium pyrophosphate, this does not exclude the possibility of articular tuberculosis.
