Contrast-associated acute kidney injury in a patient with lower respiratory tract infection

Considering the findings, we made a diagnosis of contrast-associated acute kidney injury (AKI) in the context of a viral lower respiratory tract infection. Retained intravenous contrast can be seen on a plain radiograph or a non-contrasted CT study of the abdomen more than 24 h after the administration in situations of significant renal impairment—including end stage renal disease or AKI—when the glomerular filtration rate is 45 mL/min per 1·73 m2 or less. In patients with severe chronic kidney disease or receiving renal replacement therapy risks are greater: here the benefits of imaging should be weighed against the potential harm of the contrast (video).
