Meckel's diverticulum is the most prevalent congenital abnormality of the gastrointestinal tract. Clinical symptoms can result in pain, bleeding and perforation caused by peptic ulceration. Among all imaging modalities, Tc-99m pertechnetate scintigraphy is the most sensitive method for Meckel's diverticulum diagnosis, but only mentioned in a few publications. We report the case of a young child with rectal bleeding related hemorrhagic Meckel's diverticulum. Endoscopy and ultrasound were normal. The diagnosis was done by scintigraphy with technetium revealing an accumulation of radiotracer by mucous cells in ectopic gastric mucosa, which allows a detection of Meckel's diverticulum. Our case illustrates the importance of this exam to the diagnosis of gastrointestinal bleeding with normal endoscopy.
梅克尔憩室是胃肠道最常见的先天性异常。临床症状可导致由消化性溃疡引起的疼痛、出血和穿孔。在所有影像学检查方法中，锝-99m高锝酸盐闪烁扫描是诊断梅克尔憩室最敏感的方法，但仅有少数出版物提及。我们报告一例与出血性梅克尔憩室相关的小儿直肠出血病例。内镜检查和超声检查均正常。通过锝闪烁扫描进行诊断，显示放射性示踪剂在异位胃黏膜的黏液细胞中积聚，从而得以检测出梅克尔憩室。我们的病例说明了该检查对于内镜检查正常的胃肠道出血诊断的重要性。
