Unveiling the Intrusion: An Emergent Journey Into Tuberculous Pericarditis.

We present an interesting case of mycobacterial tuberculosis pericarditis presenting as effusive constrictive pericarditis with early cardiac tamponade in a young Mexican migrant of Haitian descent. The patient underwent a pericardial window and was treated with rifampin, isoniazid, pyrazinamide, ethambutol, and vitamin B6. After further receiving steroids, the patient was doing well and was discharged home safely.
