A 69-year-old woman was hospitalized with headache. Eosinophilic granulomatosis with polyangiitis (EGPA) was diagnosed based on asthma, ground-glass opacification observed upon lung CT imaging, elevated eosinophilia (1230/μL, 15% of total white blood cell), and sinusitis. Her headache was focused on the left of the nose. Magnetic resonance imaging and angiography showed no abnormalities such as stroke or hypertrophic pachymeningitis. Digital subtraction angiography (DSA) was performed before and after treatment. Spasm was detected on the intracranial peripheral artery and painful nose area. She was treated with steroids; pain and spasm improved [Figure 1].
|Figure 1: (a and b) The image shows DSA of the left common carotid artery. Compared to post-treatment, pretreatment DSA exhibits intracranial peripheral arteries that are narrow and takes longer for visualization than the occipital artery. The distal arteries of the maxillary artery are not clearly visualized. c and d) The region distal to the maxillary artery was magnified and imaged; the pretreatment image contrast is increased for easier visualization. The infraorbital and sphenopalatine arteries show spasm (red circled area) and contrast agent pooling in the capillary phase is not observed|

Evaluation of peripheral blood vessels, especially of those in the nasal region surrounded by bones, is difficult using methods other than DSA. EGPA causes vasculitis with eosinophil infiltration, including within brain arteries. Cerebral infarction occurs in 7% of EGPA cases and can cause enlarged sequelae.  DSA can be used as reference for treatment and discovery of headache causes.
