Juvenile arteritis of extracranial arteries with hypereosinophilia

Abstract

The case history of a 23-year-old man presenting with a progressive tender swelling in both temporal regions is described. Eosinophilia varied between 28% and 48% and IgE was markedly increased (1,380 U/l). Arteriography revealed tortuous, enlarged temporal and occipital arteries intersected by stenoses. The pathology diagnosis was chronic necrotizing panarteritis of the temporal artery with pseudoaneurysms, fibrinoid necroses, scar tissue, occasional giant cells, and abundant hypereosinophilia.
