Tc-99m labeled red blood cell (RBC) scintigraphy is one of the most sensitive tests to diagnose occult gastrointestinal (GI) bleed. Visualization of gallbladder is a rare finding in this study. Most of the previously reported cases with similar false-positive finding were associated chronic renal failure, anemia, and received multiple blood transfusions. Thus, while interpreting GI bleed scan, a thorough clinical history is of utmost importance to avoid any false-positive findings. Here, we report a case of gallbladder visualization in Tc-RBC scintigraphy confirmed by single-photon emission computed tomography/computed tomography in a patient with chronic renal failure and anemia with failed renal transplant within 3 months.

锝-99m标记红细胞（RBC）闪烁扫描术是诊断隐匿性胃肠道（GI）出血最敏感的检查方法之一。在本研究中，胆囊显像是一种罕见的发现。大多数先前报道的有类似假阳性结果的病例都与慢性肾衰竭、贫血以及多次输血有关。因此，在解读胃肠道出血扫描结果时，详尽的临床病史对于避免任何假阳性结果至关重要。在此，我们报告一例慢性肾衰竭、贫血且肾移植术后3个月内移植肾失功的患者，其经单光子发射计算机断层扫描/计算机断层扫描证实，在锝标记红细胞闪烁扫描术中出现胆囊显像。
