Hepatobiliary Iminodiacetic Acid Scanning Detects Previously Unknown Hepatic Metastases from Colorectal Adenocarcinoma.

A case of previously unknown metastatic colorectal adenocarcinoma presented as focal photopenia on hepatobiliary iminodiacetic acid scintigraphy. Differential diagnosis of focal photopenia and heterogenous hepatic radiotracer uptake on hepatobiliary scintigraphy is reviewed.
