Abstract
[99mTc]Tc-PYP-RBC is used for the scintigraphy of liver hemangiomas. These images show the incidental detection of portal hypertension caused by vena cava filter obstruction on scintigraphy with [99mTc]Tc-PYP-RBC in a 31-year-old man. The patient was referred to scintigraphy because there was suspicion of liver hemangioma on ultrasound. Scintigraphy showed enlarged and tortuous abdominal veins and a high suspicion of an inferior vena cava filter obstruction was established. The patient was referred to CT where thrombosis of the inserted filter was seen, together with radiological signs of impairment in splanchnic blood flow. Scintigraphy showed signs of an inferior vena cava filter obstruction before the clinical signs were visible.
