Abstract
Primary tubercular osteomyelitis of sternum is a rare clinical entity and involvement of manubrio-sternal joint is even rarer, with only few cases reported in the literature. Tuberculous sternal involvement is seen in approximately 1% of all skeletal TB cases. We report an unusual case of primary manubrio-sternal joint tuberculosis presenting as vague anterior chest wall swelling and pain. ESR and CRP were elevated, Montoux was positive and PCR for tuberculosis was positive. Computed tomography of chest done after giving intravenous contrast showed erosion at manubrio-sternal joint with minimal soft tissue component. The patient is put on anti-tubercular drugs and is responding well with regular follow-up.
Highlights
In India, pulmonary tuberculosis accounts for 85 percent of cases and extrapulmonary tuberculosis accounts for 15 percent of cases with bone and joint involvement seen in 1 to 3 percent cases [1]
