Imaging of primary and secondary inflammatory diseases involving large and medium-sized vessels and their potential mimics: a multitechnique approach.

OBJECTIVE

The purpose of this article is to illustrate multitechnique imaging findings in patients with primary and secondary vasculitides involving large and medium-sized vessels and their mimics.

CONCLUSION

Large and medium-sized vessels are affected by many primary and secondary inflammatory disorders or mimicking conditions, often presenting similar imaging characteristics. Knowledge of distinctive imaging features such as location, length, and degree of vessel wall enhancement as well as the particular clinical settings will help the clinician in appropriately narrowing down the differential diagnosis.
