Teaching NeuroImages: Takayasu arteritis: Neuroimaging progression after immunosuppressant treatment

A 29-year-old woman presented with a 2-year history of heel pain, constitutional symptoms, and increased acute phase reactants. CT and magnetic resonance (MR) angiography revealed a thickening of aortic walls and a thread-like appearance of bilateral subclavian and common carotid arteries. The findings were consistent with Takayasu arteritis (TA)1 and the patient was prescribed methylprednisolone, followed by azathioprine. Follow-up MR angiography, 6 years later, showed an important improvement with only a mild luminal narrowing of both common carotid arteries (figures 1 and 2, A and B). TA is a large-artery inflammatory disease of unknown etiology. MRI findings parallel clinical and serologic improvement during follow-up.
