Diagnosis of Pulmonary Embolism on 99mTc-Labeled Macroaggregated Albumin Lung Imaging After Hepatic Arterial Injection for Planning of Radioembolization

Clin Nucl Med. 2022 Mar 1;47(3):e246-e248. doi: 10.1097/RLU.0000000000004026.

Abstract

A 54-year-old man with hepatocellular carcinoma from alcohol-induced cirrhosis presented with hepatic encephalopathy and refractory ascites related to decompensated liver disease. MRI confirmed disease progression adjacent the site of prior radiofrequency ablation, performed 2 years prior, with associated right hepatic vein tumor thrombus. 99mTc-labeled macroaggregated albumin lung shunt imaging performed before 90Y radioembolization identified a left lower lobe wedge-shaped defect, confirmed as pulmonary embolism on CT pulmonary angiography and MRI.
