Lymphoscintigraphy is an established modality for imaging the lymphatic system using radiocolloids and is routinely indicated to find the cause of limb lymphedema. However, in this case series, we are highlighting other less-known indications of lymphoscintigraphy like chylothorax and chyluria which present as lymphatic leaks in the thorax and abdomen, respectively. Once the site of the lymphatic leak is established by lymphoscintigraphy, definitive management like thoracic duct ligation or sclerotherapy can be done. The other indication discussed is postrenal transplant perinephric fluid collection which can be challenging to confirm whether it is urinoma, lymphocele, or any other collection. And finally, sentinel lymph node localization is another, now, well-established indication of lymphoscintigraphy.
淋巴闪烁显像术是一种利用放射性胶体对淋巴系统进行成像的既定方法，常用于查找肢体淋巴水肿的病因。然而，在本病例系列中，我们着重介绍淋巴闪烁显像术其他鲜为人知的适应证，如乳糜胸和乳糜尿，它们分别表现为胸部和腹部的淋巴漏。一旦通过淋巴闪烁显像术确定了淋巴漏的部位，就可以进行诸如胸导管结扎或硬化疗法等确定性治疗。所讨论的另一个适应证是肾移植后肾周积液，要确定其是尿囊肿、淋巴囊肿还是其他类型的积液颇具挑战性。最后，前哨淋巴结定位是淋巴闪烁显像术如今已确立的另一适应证。
