Fortuitous findings of Tc-99m PIPIDA hepatobiliary scintigraphy

Hepatobiliary scintigraphy using Tc-99m labeled radiopharmaceuticals is employed primarily for the diagnosis of acute cholecystitis and for demonstration of biliary tract potency. This produce may also provide diagnostic information in the identification of unusual or atypical hepatobiliary disorders; frequently, this occurs as an incidental result of the test. We present five cases in which trauma, infection, or obstructive abnormalities were diagnosed fortuitously.
