The phantom kidney is a "kidney-like" apparition which may be seen in dynamic renal scintigraphy typically in post-nephrectomy patients or in patients with unilateral renal agenesis. We report a case of a phantom kidney demonstrated in the angiographic phase of renal scintigraphy with 99mTc-dimercaptosuccinic acid (99mTc-DMSA) in a patient who was nephrectomized 14 years previously. After comparison with the CT images, we conclude that our patient's finding was caused by an increased mesenteric vascularity, possibly postprandial. Several conditions which may cause the phantom kidney effect, have been reported, but increased mesenteric vascularity seems to be the most common cause.
假肾是一种“肾样”影像，通常在肾动态闪烁显像中可见，多见于肾切除术后患者或单侧肾缺如患者。我们报告一例在肾闪烁显像血管造影期用99m锝-二巯基丁二酸（99mTc-DMSA）显示假肾的病例，该患者14年前已行肾切除术。与CT图像对比后，我们得出结论，患者的这一发现是由肠系膜血管增多引起的，可能与餐后状态有关。已有报道多种可能导致假肾效应的情况，但肠系膜血管增多似乎是最常见的原因。
