Widespread malignancy with relatively normal kidneys showing contrast enhancement
Case Discussion
Contrast-induced acute kidney injury (CI-AKI) is uncommon and usually in patients with pre-existing renal dysfunction (ie eGFR < 30), dehydration and/or large volume contrast injection (> 300mls at one sitting) such as my occur in cardiac, vascular or neuro-interventional procedures.
