Radiolabeled red blood cell (RBC) scintigraphy is a common study to detect and localize gastrointestinal hemorrhage. There are many potential entities that may result in false-positive RBC scintigraphy. Here, we present a case of enlarged feeding vessels of omental carcinomatosis which scintigraphically might be mistaken as intraluminal bowel activity and thus active hemorrhage. This case highlights the importance of reviewing correlative imaging in patients with a large neoplastic burden.
放射性标记红细胞（RBC）闪烁扫描是检测和定位胃肠道出血的常用检查。有许多潜在情况可能导致RBC闪烁扫描出现假阳性。在此，我们报告一例网膜转移癌供血血管增粗的病例，在闪烁扫描中可能会被误认为肠腔内活动，进而被误诊为活动性出血。该病例强调了对肿瘤负荷较大患者的相关影像进行评估的重要性。
