TY - CHAP M1 - Book, Section TI - The Vascular System A1 - Wells, Robert G. PY - 2015 T2 - Diagnostic Imaging of Infants and Children AB - The term vasculitis refers to inflammation of blood vessels. There are various classification schemes for noninfectious vasculitis, based on the sizes of the blood vessels typically involved and the pathology of the lesions (Table 13-1). Takayasu disease is the most important large vessel vasculitis in children. Kawasaki disease, polyarteritis nodosa, and primary central nervous system (CNS) vasculitis of childhood are vasculitides that primarily involve mediumsize vessels. Examples of small vessel vasculitis include Henoch-Schönlein purpura, Wegener granulomatosis, Churg-Strauss syndrome, and microscopic polyangiitis. There is considerable variation in the organ systems most prominently affected by the various vasculitides. Constitutional symptoms, fever, and skin lesions are common with these disorders.1 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/29 UR - accesspediatrics.mhmedical.com/content.aspx?aid=1148948190 ER -
