Acure renal failure post IV contrast injection: CT findings

Case contributed by Dr Chris O'Donnell

Presentation

Acute renal failure (anuria) 48 hours post IV radiographic contrast injection for assessment of disseminated malignancy. eGFR of 35.

Patient Data

Age: 75
Gender: Male

CT scan performed 2 days later prior to biopsy, no IV contrast administered

Modality: CT

Residual contrast in the renal parenchyma but not the collecting systems without contrast in other organs or blood vessels despite isolated IV contrast injection 2 days previously.

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.
