A patient with multiple episodes of gastrointestinal bleeding underwent Tc-labeled red blood cell scintigraphy to detect the source of bleeding, which showed a focally increased activity in the upper midabdomen. SPECT/CT demonstrated that the activity was located in the pancreatic head. Angiography confirmed the diagnosis of pancreatic arteriovenous malformation. After transarterial embolization therapy, the patient no longer had bleeding episode. Based on the present case, pancreatic arteriovenous malformation should be included as differential diagnosis during Tc-red blood cell scintigraphy.
一位反复发生胃肠道出血的患者接受了 Tc 标记的红细胞闪烁显像术来检测出血源，结果显示中上腹部有局灶性放射性增高。SPECT/CT 显示活性位于胰头部。血管造影证实了胰腺动静脉畸形的诊断。经动脉栓塞治疗后，患者不再有出血发作。基于本病例，在 Tc 红细胞闪烁显像术时应将胰腺动静脉畸形作为鉴别诊断之一。
