Polyarteritis Nodosa: MythThe philosophy underlying this statement is accurate (i.e.,biopsies of symptomatic organs have a higher yield thanbiopsies of uninvolved organs).The statement is false, however.A study of 175 consecutive sural nerve biopsies from onecenter addressed the question of how often sural nervebiopsies revealed necrotizing vasculitis among patientsultimately diagnosed as having systemic vasculitis.Gorson KC, Hedley-White ET, Skinner MM Case records of the Massachusetts General Hospital. N Engl J Med M917-923, 2001
Polyarteritis Nodosa: MythEven among patients with symptomatic neuropathy andabnormal electromyograms (EMGs), the yield of a suralnerve biopsy was only 45%When systemic vasculitis is suspected, a negative suralnerve biopsy does not exclude the diagnosis (even in asymptomatic patient).If nerve conduction velocity (NCV) studies show apattern consistent with mononeuritis multiplexand the patient has other clinical features compatible withvasculitis, that is probably the correct diagnosis.
