A 42-year-old woman with advanced alcoholic liver cirrhosis was referred for a Tc-99m-labeled red blood cell (RBC) abdominal scan due to tarry stool passage. The Tc-99m RBC scan revealed a tangled linear radioactivity accumulation, extending from the right epigastric area to the right lower pelvic region. The integrated single-photon emission computed tomography/computed tomography (SPECT/CT) with 3D volume rendering imaging and CT bone segmentation display confirmed the portosystemic collateral circulation.
