We described CT and MRI findings of various refractory vasculitis. Refractory vasculitis must be divided into two categories including one group with major vascular involvement and another one with small or microvascular involvement. In cases with major vessel involvement such as Takayasu's arteritis, Kawasaki disease or vasculo-Behçet disease, CT and MRI depicted direct findings of vessels itself including stenosis, obstruction, aneurysm, and wall thickening. On the other hand, CT and MRI showed various extravascular findings in cases with small or microvascular involvement, such as CNS involvement in collagen vascular disease, pulmonary lesions in Wegener's granulomatosis and Churg-Strauss syndrome, and peritoneal lesion in SLE. Our results suggest that CT and MRI findings reflect various vascular condition of refractory vasculitis and correspond to various pathology.
