An 82-year-old man had his third episode of melanotic stool. Two previous workups had failed to localize the source of bleeding. A Tc-99m labeled RBC scan visualized the gallbladder early in the study. Administration of sincalide visually decreased the activity, confirming gallbladder activity. Three months later, at his second surgery, hepatic metastases were finally identified as the source of bleeding. In retrospect, the hepatic activity is inhomogeneous with at least two cold defects that could have represented hepatic metastases.
一名82岁男性出现了第三次黑便。前两次检查未能确定出血源。在一项锝-99m标记红细胞扫描研究中，胆囊在早期显影。注射辛卡利特后，图像上的活性降低，证实为胆囊活性。三个月后，在他的第二次手术中，最终确定肝转移为出血源。回顾来看，肝脏活性不均匀，至少有两个冷区缺损，可能代表肝转移。
