A 76-year-old woman presented after 1 day of melena and anemia. A Meckel's scan revealed an upper mid abdominal focus of activity that paralleled stomach activity. Later, the surgeon removed the corresponding lesion in the mid ilium. Pathology confirmed that the lesion was a carcinoid tumor, not ectopic gastric mucosa. The false-positive Meckel's scan had revealed the true source of gastrointestinal bleeding and an unsuspected solitary carcinoid tumor. This is the third published case of a carcinoid tumor discovered by a false-positive Meckel's scan.
一名76岁女性在出现黑便和贫血1天后前来就诊。梅克尔扫描显示上腹部中部有一个与胃活动同步的活动灶。后来，外科医生在回肠中部切除了相应病变。病理证实该病变为类癌肿瘤，而非异位胃黏膜。梅克尔扫描的假阳性结果揭示了胃肠道出血的真正来源以及一个此前未被怀疑的孤立类癌肿瘤。这是第三例通过梅克尔扫描假阳性发现类癌肿瘤的已发表病例。
