Technetium-99m-medronate uptake in hepatic necrosis associated with Budd-Chiari syndrome

A 99mTc-MDP bone scan performed on a 52-yr-old female for possible bone metastasis revealed prominent hepatic uptake. Subsequently, a 99mTc-SC scan revealed tracer uptake in the caudate lobe with diminished uptake in the remainder of the liver. Further imaging with Doppler ultrasound and hepatic venography confirmed a diagnosis of Budd-Chiari syndrome. Hepatic necrosis, demonstrated on CT imaging, was secondary to Budd-Chiari syndrome and was felt to be the cause of 99mTc-MDP hepatic uptake in this patient.
