A 41-year-old woman with CNS vasculitis. 3T-HRMRI pre- and postgadolinium (A and B) T1-weighted arterial wall coronal images of terminal supraclinoid ICA and proximal M1 with strong smooth, concentric wall enhancement and thickening. C, MRA shows stenosis of the lumen and narrowing of M1 and the terminal supraclinoid ICA. Follow-up at 12 months. D and E, Pre- and post-gadolinium T1WI with near resolution of enhancement on coronal view. F, MRA with interval resolution of luminal narrowing and stenosis.

A 61-year-old woman with RCVS. 3T-HRMRI postgadolinium T1-weighted arterial wall with fat suppression and saturation band. A and B, Axial images in the same planes show bilateral A1, M1, and P2 with diffuse uniform wall thickening and wall narrowing with mild enhancement. C, MRA shows corresponding bilateral A1, M1, posterior communicating artery, and P2 narrowing. Follow-up vessel wall imaging at 3 months. D and E, Postgadolinium axial imaging with interval near resolution of uniform wall thickening and wall narrowing in the A1 and M1 segments and resolution of uniform wall thickening and wall narrowing in the P2 segment. F, Follow-up MRA with resolution of luminal narrowing with patent bilateral A1, M1, posterior communicating artery, and P2.
