A 58-year-old man was referred for selective internal radiation therapy for locally advanced unresectable hepatocellular carcinoma. Intra-arterial particle perfusion scintigraphy was performed with SPECT/CT following intra-arterial injection of 99mTc macroaggregated albumin. Angiography demonstrated a hepatic falciform artery, a feeding artery of the ligamentum teres, whereas scintigraphy demonstrated tracer uptake in the mid–anterior abdominal wall. The hepatic falciform artery was subsequently embolized and the repeat angiogram confirmed successful occlusion. Subsequent post–selective internal radiation therapy PET/CT images did not reveal any tracer uptake in the mid–anterior abdominal wall.
