Takayasu arteritis presented with acute febrile pericardial effusion

We report the clinical and radiographic findings of Takayasu arteritis (TA) presented with acute febrile pericardial effusion. Our case is unique in that acute pericardial effusion developed in the absence of other intracardiac abnormalities as an initial manifestation of TA. While pericardial effusion is infrequently related with TA, TA should be considered as one of causes of acute febrile pericardial effusion in especially young women.
