Pseudo-vascular tumor in a renal flow study.
A case in which, for the first time, the superior mesenteric artery caused an appearance mimicking vascular tumor on a kidney radionuclide angiogram (RNA) obtained posteriorly, is reported. A subsequent contrast arteriogram showed that the superior mesenteric artery caused that appearance and confusion with possible vascular tumor on RNA. No similar cases with mesenteric blush simulating vascular tumor have been found in the literature. Mesenteric blushes on RNAs obtained posteriorly have been described only in cases of kidney agenesis and post-nephrectomy. This pattern should be kept in mind when interpreting RNAs to avoid subjecting patients to invasive diagnostic procedures.
