Takayasu's Arteritis with Isolated Pulmonary Artery Involvement in a Middle-Aged Asian Woman with Hepatitis B and Latent Tuberculosis Infection.

We report a rare case of Takayasu's arteritis with isolated pulmonary artery stenosis in the presence of active hepatitis B and latent Mycobacterium tuberculosis infection in a middle-aged Asian woman who initially presented with severe dyspnea on exertion and recurrent syncope, occasional burning chest pains, and fatigue. Therapy of the active hepatitis B and latent M. tuberculosis infection together with a course of methotrexate led to a slight reversal of the symptoms, as angioplasty with or without stenting was not an option. The constellation described here hints at the possible link between hepatitis B and M. tuberculosis infection and the development of Takayasu's arteritis. The case also supports the little evidence available indicating that treatment of active hepatitis B infection could positively influence the course of Takayasu's arteritis.
