Three children are reported with vesical filling defects on scintigraphy secondary to extrinsic causes. In two chronically constipated individuals undergoing bone scintigraphy, the extrinsic pressure on the bladder by rectosigmoid feces resulted in simulation of intrinsic space-occupying lesions. Focal attenuation of bladder activity on nuclear cystography by the metal distal hook of a Harrington rod also produced the pseudo-appearance of a vesical filling defect in a third patient.
据报道，有三名儿童因外在原因在闪烁扫描中出现膀胱充盈缺损。在两名接受骨闪烁扫描的慢性便秘患者中，乙状结肠直肠内的粪便对膀胱的外在压力导致模拟内在占位性病变。在第三名患者中，哈灵顿棒的金属远端钩在核膀胱造影中造成膀胱活动的局灶性衰减，也产生了膀胱充盈缺损的假像。
