Extraosseous Bone Tracer Accumulation of the Liver on 99mTc-HDP Bone Scintigraphy in Intermittent Bleeding After Iatrogenic Liver Injury

Abstract

A 69-year-old man with common bile duct cancer and deep jaundice had complained of abdominal pain after percutaneous transhepatic biliary drainage. The laboratory workup showed reduction of serum hemoglobin level after the procedure. A 99mTc-hydroxy diphosphonate bone scan was performed for further evaluation of common bile duct cancer, and there was no abnormality of the skeletal structures. However, diffuse and hazy increased radiotracer uptake was detected on the liver. Follow-up contrast-enhanced CT revealed hematoma and subcapsular hemorrhage of the liver.
