Diagnostic error due to vicarious excretion of rectal iodinated contrast

Abstract:
Introduction of iodinated contrast into the intact colon is not expected to result in imaging-visible renal excretion of this contrast and is a phenomenon that has only rarely been described. We present a case in which such vicarious renal excretion was misinterpreted as a recto-vesical fistula which resulted in unnecessary delay in the patient's management.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
