Abdominal varices consisting of a caput medusae and dilated mesenteric veins resulted in pooling of Tc-99m tagged red blood cells (RBC) within these dilated vessels in a 57-year-old man with severe Laennec's cirrhosis. The atypical radiotracer localization within the abdomen mimicked an acute gastrointestinal hemorrhage. Clinical suspicion and careful evaluation of scintigraphic gastrointestinal bleeding studies will avoid false-positive interpretations.
一名患有严重Laennec肝硬化的57岁男性，其腹部静脉曲张表现为海蛇头和扩张的肠系膜静脉，导致锝-99m标记的红细胞（RBC）在这些扩张的血管内聚集。腹部内这种非典型的放射性示踪剂定位类似于急性胃肠道出血。临床怀疑并仔细评估闪烁扫描胃肠道出血研究将避免假阳性解读。
