Case report: We report a rare case of dilated cardiomyopathy in an 18-year-old girl who was later diagnosed to have Takayasu arteritis using doppler and computed tomography and subsequently treated by immunosuppressant therapy with prednisolone and methotrexate. Discussion: Takayasu arteritis is a large vessel vasculitis in which the inflammatory process involves aorta and major branches. The cause is largely unknown. Dilated cardiomyopathy (DCM) is, however, reported to be seen in only 5-6% of cases of Takayasu arteritis (Jameson et al., 2012). Ultrasonography with doppler, computed tomography and Magnetic Resonance Imaging (MRI) can be used for the early diagnosis of the disease. Conclusion: In a case of dilated cardiomyopathy in young female screening for systemic vasculitis should be done as timely initiation of immunosuppressant therapy can reduce the development of other complications of Takayasu arteritis.
