4. Polymyalgia rheumatica and giant cell arteritis Polymyalgia rheumatica is an inflammatory condition that can manifest with interspinous bursitis. 1 Giant cell arteritis is a granulomatous vasculitis that affects medium and large vessels and occurs in 16 to 21% of patients with PMR. 2 MRA can show narrowing of the affected artery and contrast-enhanced MRI can reveal surrounding inflammatory changes. Color Doppler ultrasound can show arterial wall edema (“halo sign”), which can persist during steroid therapy. 3 Ginat et al.
