Benign transient eosinophilia following intravenous urography

M. E. Vincent, S. G. Gerzof and A. H. Robbins

Eosinophilia, a component of the allergic response, may occur after the use of iodinated radiographic contrast media for intravenous urography. A benign transient elevation in differential eosinophil count was seen in 21 of 101 patients following the injection of iodinated contrast agents for that purpose.
