A false-positive 111In-labeled leukocyte scan was obtained in a girl with cystic fibrosis and infection. There was focal accumulation of 111In activity in the abdomen and marked pulmonary uptake. Surgical exploration and postmortem examination revealed no abdominal abnormality. The abnormal activity was apparently due to swallowed sputum which contained labeled leukocytes. Broader clinical implications are discussed.
一名患有囊性纤维化并伴有感染的女孩进行了铟-111标记白细胞扫描，结果出现假阳性。腹部有铟-111活性的局灶性积聚，肺部摄取明显。手术探查和尸检未发现腹部异常。异常活性显然是由于吞咽了含有标记白细胞的痰液所致。文中讨论了更广泛的临床意义。
