A crying liver: a scan pattern mimicking spontaneous perforation of the biliary ducts.

Abstract

A 2-month-old infant was referred for hepatobiliary scintigraphy due to ascites of unknown cause. The top differential diagnosis was spontaneous perforation of the biliary ducts. Delayed images up to 4 hours were against this diagnosis showing normal distribution of the radiotracer throughout the bowel. However, on delayed images, the scan showed mild tracer retention in the ascites confirmed by SPECT/CT images. Surprisingly, the exploratory abdominal surgery revealed an intact hepatobiliary system, pointing toward other possible etiologies. Second-review surgery was performed due to uncontrolled progressive ascites showing congestive hepatopathy and biliary leak from the hepatic surface suggestive of the "crying liver".
